Abstract
Official abstract text for this publication.
A start control device, which is a control device, includes: a first adjustment processing unit configured to execute a first adjustment process of instructing at least one of a brake device and a drive device to increase a braking/driving force when the braking/driving force is negative and the vehicle is stopped; and a second adjustment processing unit configured to start a second adjustment process of instructing at least one of the brake device and the drive device to increase the braking/driving force at a speed lower than an increasing speed of the braking/driving force before end of the first adjustment process on condition that the braking/driving force has become greater than or equal to a determination braking/driving force by the increase in the braking/driving force accompanying the execution of the first adjustment process.

The invention claimed is: 1. A vehicle control device that starts a vehicle by controlling a brake device and a drive device; the vehicle control device comprising: in a case where a force that becomes negative when a braking force of the vehicle exceeds a driving force of the vehicle and becomes positive when the braking force of the vehicle falls below the driving force of the vehicle is defined as a braking-driving force, a first adjustment processing unit configured to execute a first adjustment process of instructing to increase the braking-driving force by increasing the driving force to be instructed to the driving device without reducing the braking force to be instructed to the braking device when the braking-driving force is negative and the vehicle is stopped; and a second adjustment processing unit configured to start a second adjustment process of instructing at least one of the brake device and the drive device to increase the braking-driving force at a speed lower than an increasing speed of the braking-driving force before end of the first adjustment process on condition that the braking-driving force has become greater than or equal to a determination braking-driving force smaller than zero due to an increase in the braking-driving force accompanying the execution of the first adjustment process. 2. The vehicle control device according to claim 1 , further comprising a start determination unit configured to determine whether the vehicle has started, wherein the second adjustment processing unit starts the second adjustment process on condition that the braking-driving force is greater than or equal to the determination braking-driving force and determination is made that the vehicle has started. 3. The vehicle control device according to claim 2 , further comprising: a target attainment determination unit configured to determine whether one of the braking force and the driving force of the vehicle has reached a target value during execution of the second adjustment process; and a third adjustment processing unit configured to start a third adjustment process of instructing one of the brake device and the drive device to increase the braking-driving force on condition that determination is made that the one of the braking force and the driving force has reached the target value, wherein in the third adjustment process, the third adjustment processing unit instructs the one of the brake device and the drive device to increase the braking-driving force at the same speed as the increasing speed of the braking-driving force before end of the second adjustment process. 4. The vehicle control device according to claim 2 , further comprising: a target attainment determination unit configured to determine whether one of the braking force and the driving force of the vehicle has reached a target value during execution of the second adjustment process; and a third adjustment processing unit configured to start a third adjustment process of instructing one of the brake device and the drive device to increase the braking-driving force on condition that determination is made that the one of the braking force and the driving force has reached the target value, wherein in the third adjustment process, the third adjustment processing unit instructs the one of the brake device and the drive device to increase the braking-driving force at a lower speed than the increasing speed of the braking-driving force before end of the second adjustment process. 5. The vehicle control device according to claim 1 , further comprising: a target attainment determination unit configured to determine whether one of the braking force and the driving force of the vehicle has reached a target value during execution of the second adjustment process; and a third adjustment processing unit configured to start a third adjustment process of instructing one of the brake device and the drive device to increase the braking-driving force on condition that determination is made that the one of the braking force and the driving force has reached the target value, wherein in the third adjustment process, the third adjustment processing unit instructs the one of the brake device and the drive device to increase the braking-driving force at the same speed as the increasing speed of the braking-driving force before end of the second adjustment process. 6. The vehicle control device according to claim 1 , further comprising: a target attainment determination unit configured to determine whether one of the braking force and the driving force of the vehicle has reached a target value during execution of the second adjustment process; and a third adjustment processing unit configured to start a third adjustment process of instructing one of the brake device and the drive device to increase the braking-driving force on condition that determination is made that the one of the braking force and the driving force has reached the target value, wherein in the third adjustment process, the third adjustment processing unit instructs the one of the brake device and the drive device to increase the braking-driving force at a lower speed than the increasing speed of the braking-driving force before end of the second adjustment process. 7. A vehicle control device that starts a vehicle by controlling a brake device and a drive device; the vehicle control device comprising: in a case where a force that becomes negative when a braking force of the vehicle exceeds a driving force of the vehicle and becomes positive when the braking force of the vehicle falls below the driving force of the vehicle is defined as a braking-driving force, a first adjustment processing unit configured to execute a first adjustment process of instructing at least one of the brake device and the drive device to increase the braking-driving force when the braking-driving force is negative and the vehicle is stopped; and a second adjustment processing unit configured to start a second adjustment process of instructing at least one of the brake device and the drive device to increase the braking-driving force at a speed lower than an increasing speed of the braking-driving force before end of the first adjustment process by decreasing the increasing speed of the driving force without decreasing the decreasing speed of the braking force on condition that the braking-driving force has become greater than or equal to a determination braking-driving force smaller than zero due to an increase in the braking-driving force accompanying the execution of the first adjustment process. 8. The vehicle control device according to claim 7 , further comprising a start determination unit configured to determine whether the vehicle has started, wherein the second adjustment processing unit starts the second adjustment process on condition that the braking-driving force is greater than or equal to the determination braking-driving force and determination is made that the vehicle has started. 9. The vehicle control device according to claim 8 , further comprising: a target attainment determination unit configured to determine whether one of the braking force and the driving force of the vehicle has reached a target value during execution of the second adjustment process; and a third adjustment processing unit configured to start a third adjustment process of instructing one of the brake device and the drive device to increase the braking-driving force on condition that determination is made that the one of the braking force and the driving force has reached the target value, wherein in the third adjustment process, the third adjustment processing unit instructs the one of the brake device and the drive device to incr
