Abstract

A distance sensor detects a distance to an object in front of a vehicle. An ECU executes pre-crash control when the detected distance becomes equal to or smaller than a prescribed value. A regeneration level selector selects a regeneration level of a motor in accordance with driver's operation. A motor makes regenerative braking force at the time of turning off an accelerator larger when the selected regeneration level is high than when the selected regeneration level is low. The ECU makes the prescribed value larger when the selected regeneration level is low than when the selected regeneration level is high.

First claim

What is claimed is:

1. A vehicle, comprising:
a motor serving as a driving force source for the vehicle;
a detector configured to detect a distance to an object in front of the vehicle;
an electronic control unit configured to execute pre-crash control when the detected distance detected by the detector becomes equal to or smaller than a prescribed value; and
a selecting unit configured to select a regeneration level of the motor in accordance with an operation of a driver of the vehicle, wherein
the motor makes a regenerative braking force at a time of turning off an accelerator larger when the selected regeneration level is high compared to when the selected regeneration level is low, and
the electronic control unit sets the prescribed value based on the selected regeneration level so as to make the prescribed value larger when the selected regeneration level is low compared to when the selected regeneration level is high.

2. The vehicle according to claim 1 , wherein
even while the accelerator is on, the electronic control unit executes the pre-crash control when the detected distance becomes equal to or smaller than the prescribed value.

3. The vehicle according to claim 1 , wherein
the electronic control unit provides the driver of the vehicle with a warning as the pre-crash control.

4. The vehicle according to claim 1 , wherein
the electronic control unit decelerates the vehicle as the pre-crash control.

5. The vehicle according to claim 1 , wherein
the electronic control unit sets the prescribed value based on the selected regeneration level and a detected vehicle speed.

6. A vehicle, comprising:
a motor serving as a driving force source for the vehicle;
a detector configured to detect a distance to an object in front of the vehicle;
an electronic control unit configured to execute adaptive cruise control as pre-crash control such that the detected distance detected by the detector has a prescribed value; and
a selecting unit configured to select a regeneration level of the motor in accordance with an operation of a driver of the vehicle, wherein
the motor makes a regenerative braking force at a time of deceleration during the adaptive cruise control larger when the selected regeneration level is high compared to when the selected regeneration level is low, and
the electronic control unit sets the prescribed value based on the selected regeneration level so as to make the prescribed value larger when the selected regeneration level is low compared to when the selected regeneration level is high.
