Patent number: 10328803Abstract: the control device for electric vehicle in the first embodiment, in the electric vehicle including the motor that functions as the traveling driving source and provides a regenerative braking force to the vehicle, and the friction brakes that provide the friction braking force to the vehicle, detects the motor rotation speed proportionate to a running speed of this electric vehicle, estimates the disturbance torque that acts on the motor, and performs the control such that the motor torque command value converges to the disturbance torque estimated value as the motor rotation speed decreases. Then, when the motor rotation speed becomes almost 0, the control device performs the control such that the friction-braking-amount command value with respect to the friction brakes converges to a value determined on the basis of the disturbance torque estimated value, and causes the motor torque command value to converge to almost 0.Type: GrantFiled: August 10, 2016Date of Patent: June 25, 2019Assignee: NISSAN MOTOR CO., LTD.Inventors: Hiroyuki Komatsu, Ken Itou, Takashi Nakajima, Yuuji Katsumata, Akira Sawada

Patent number: 10279787Abstract: A method for carrying out a driver-independent brake force holding function in a motor vehicle when the motor vehicle is at a standstill on a roadway that is inclined in the vehicle longitudinal direction. The brake force, maintained independently of the driver, is reduced when a release condition is met. In the method, the uphill distance, which corresponds to the spacing or the distance from the neighboring vehicle in the uphill direction, is ascertained with the aid of a first distance sensor system. If the uphill distance falls below a predetermined limiting value, the brake force is reduced before the release condition is met, so that the motor vehicle moves.Type: GrantFiled: September 16, 2016Date of Patent: May 7, 2019Assignee: ROBERT BOSCH GMBHInventor: Frank Baehrle-Miller
