  • Publication number: 20160264003
    Abstract: When a regenerative braking force is controlled based on a target stop position or a target following distance, a driver may have an uncomfortable feeling if a vehicle is stopped or a following distance is secured by the regenerative braking force only and thus, the driver is prompted to perform a brake pedal operation and the driver adjusts deceleration by himself to reduce the driver's uncomfortable feeling. Regenerative deceleration by a motor when the driver operates neither accelerator pedal nor brake pedal is controlled to be smaller than deceleration needed to stop in the target stop position or deceleration needed to reduce a relative speed to the preceding vehicle to zero at the target following distance.
