Abstract

A computer-implemented method of operating a vehicle. The method includes receiving a first signal from a pedal indicating no pressure is exerted on the pedal, the pedal, when pressed, configured to provide a manual input to an operation of the vehicle; determining whether the vehicle is within a threshold distance from an object ahead of the vehicle; if the distance between the vehicle and the object is within the threshold distance, engaging regenerative braking to reduce the speed of the vehicle; and if the distance between the vehicle and the object is above the threshold distance, preventing regenerative braking from being engaged to allow the vehicle to coast.

First claim

What is claimed is:

1 . A computer-implemented method of operating a vehicle comprising:
receiving a first signal from a pedal indicating no pressure is exerted on the pedal, the pedal, when pressed, configured to provide a manual input to an operation of the vehicle; determining whether the vehicle is within a threshold distance from an object ahead of the vehicle; if the distance between the vehicle and the object is within the threshold distance, engaging regenerative braking to reduce the speed of the vehicle; and if the distance between the vehicle and the object is above the threshold distance, preventing regenerative braking from being engaged to allow the vehicle to coast.

2 . The computer-implemented method of claim 1 , further comprising:
receiving a second signal from a distance sensor of the vehicle; and calculating the distance between the object and the vehicle based on the second signal.

3 . The computer-implemented method of claim 1 , further comprising:
receiving image data from a camera of the vehicle; and determining the distance between the object and the vehicle based on the image data.

4 . The computer-implemented method of claim 1 , further comprising:
receiving speed data from a speed sensor of the vehicle; and determining the speed of the vehicle based on the speed data, wherein the threshold distance is set based on the speed of the vehicle.

5 . The computer-implemented method of claim 1 , wherein engaging regenerative braking to reduce the speed of the vehicle comprises transmitting a third signal to a motor of the vehicle.

6 . The computer-implemented method of claim 1 , wherein preventing regenerative braking from being engaged comprises transmitting a zero-torque command to a motor of the vehicle.

7 . The computer-implemented method of claim 1 , wherein if the distance between the vehicle and the object is within the threshold distance, automatically engaging an adaptive cruise control of the vehicle.

8 . A vehicle comprising:
a distance sensor configured to detect a distance between the vehicle and an object in front of the vehicle; a pedal configured to increase the speed of the vehicle when pressed; a communication module configured to transmit signals from the distance sensor and the pedal to a processor; and a non-transitory storage configured to store instructions, which when executed by the processor, cause the processor to perform a method comprising:
determining whether the vehicle is within a threshold distance from an object ahead of the vehicle;
if the distance between the vehicle and the object is within the threshold distance, engaging regenerative braking to reduce the speed of the vehicle; and
if the distance between the vehicle and the object is above the threshold distance, preventing regenerative braking from being engaged to allow the vehicle to coast.

9 . The vehicle of claim 8 , wherein the method further comprises:
receiving image data from a camera of the vehicle; and determining the distance between the object and the vehicle based on the image data.

10 . The vehicle of claim 8 , wherein the method further comprises:
receiving speed data from a speed sensor of the vehicle; and determining the speed of the vehicle based on the speed data.

11 . The vehicle of claim 10 , wherein the threshold distance is set based on the speed of the vehicle.

12 . The vehicle of claim 8 , wherein engaging regenerative braking to reduce the speed of the vehicle comprises transmitting a third signal to a motor of the vehicle.

13 . The vehicle of claim 8 , wherein preventing regenerative braking from being engaged comprises transmitting a zero-torque command to a motor of the vehicle.

14 . The vehicle of claim 8 , wherein if the distance between the vehicle and the object is within the threshold distance, automatically engaging an adaptive cruise control of the vehicle.

15 . The vehicle of claim 8 , further comprising:
a controller in communication with the processor; a motor and brakes, both in communication with the controller; wherein the method further comprises the processor transmitting a control signal to the controller; and the controller controls the motor and brakes in response to the control signal.
