Publication number: 20160152157Abstract: A method and system is provided for determining a direction of movement of an electric vehicle. The method and system includes determining the direction of rotation and the direction of torque of a motor shaft, determining an operating gear of the vehicle, and determining a previous direction of movement of the vehicle. The method and system then determines if the vehicle is moving forward or backwards. The method and system also determines whether the vehicle is motoring (i.e., converting electric power to mechanical power) or generating (i.e., converting mechanical power into electric power).Type: ApplicationFiled: December 2, 2014Publication date: June 2, 2016Inventors: Qingyuan Li, Kevin Wu, Ravikumar Bhadange, Achim Frech, Aaron Saylor

Patent number: 9061663Abstract: A system for stabilizing a sway of a trailer attached to a vehicle. In one embodiment, the system includes a controller, a plurality of sensors in electronic communication with the controller and transmitting sensor data to the controller, a torque vectoring device in electronic communication with the controller, and a computer readable memory storing instructions executed by the controller. The instructions cause the controller to evaluate the sensor data received from the sensors to determine a current vehicle yaw rate, a target vehicle yaw rate, and a yaw rate error of the vehicle. The instructions further cause the controller to determine if the vehicle is traveling in a straight line, to determine a torque distribution signal, and to transmit this signal to the torque vectoring device to stabilize the sway of the trailer without braking the vehicle.Type: GrantFiled: October 27, 2010Date of Patent: June 23, 2015Assignee: Robert Bosch GmbHInventor: Hsien-Cheng (Kevin) Wu

Patent number: 8311693Abstract: Systems and methods for stabilizing a hybrid electric vehicle (“HEV”) towing a trailer. One system includes a regenerative braking system, a non-regenerative braking system, and a stabilization system. The stabilization system determines a direction of rotation and a speed of the HEV and compares the HEV's speed to a predetermined low speed threshold value and a predetermined high speed threshold value. The stabilization system instructs the regenerative braking system to brake at least one wheel when the speed is less than or equal to the predetermined low speed threshold value and instructs the regenerative braking system to brake at least one wheel opposite the direction of rotation and at least one of the regenerative braking system and the non-regenerative braking system to provide an extra stabilizing braking torque to at least one wheel opposite the direction of rotation when the speed is greater than the predetermined high speed threshold value.Type: GrantFiled: November 19, 2010Date of Patent: November 13, 2012Assignee: Robert Bosch GmbHInventors: Hsien-Cheng (Kevin) Wu, Bo Xu

Patent number: 8285465Abstract: A cooperative traction control system that integrates throttle control and torque distribution. The system also uses dual slip controllers and methods that involve controlling the distribution of torque between wheels in the front and rear axles of a vehicle and a relatively small or no adjustment of the engine throttle (or, more generally, engine torque output) to reduce wheel slip. The control is cooperative in the sense that two controllers—a front axle torque controller and a rear axle torque controller—work together (or are controlled together) to reduce wheel slip and thereby achieve improved straight-line movement of a vehicle from a standstill.Type: GrantFiled: September 9, 2009Date of Patent: October 9, 2012Assignee: Robert Bosch GmbHInventors: Hsien-cheng (Kevin) Wu, Qingyuan Li, Jin-jae Chen
