Patent number: 11845422Abstract: A method includes determining a desired yaw moment to be applied to an ego vehicle during travel. The method also includes identifying yaw moment changes that are achievable using different torque vectoring techniques supported by the ego vehicle. The method further includes selecting at least one of the torque vectoring techniques based on the identified yaw moment changes. In addition, the method includes using the at least one selected torque vectoring technique to obtain the desired yaw moment and create lateral movement of the ego vehicle during the travel. In some cases, a desired response time associated with the lateral movement of the ego vehicle may be used, where steering control provides a faster response time and torque vectoring control provides a slower response time. The at least one torque vectoring technique may be selected based on different energy efficiencies associated with different ones of the torque vectoring techniques.Type: GrantFiled: September 29, 2021Date of Patent: December 19, 2023Assignee: Canoo Technologies Inc.Inventors: Kilsoo Kim, Jongmoo Choi, Vishal U.

Patent number: 11827218Abstract: Disclosed is a method intended to regulate the speed of a vehicle with at least partially automated driving and knowing the radius of curvature of a future segment which it is about to take on its route. This method comprises a step (10-90) which involves regulating the speed of the vehicle in accordance with a speed setpoint and, in the event that a radius of curvature of the future segment representative of a bend is detected, determining a maximum transverse acceleration that the vehicle can undergo in the bend depending on the speed setpoint, then a maximum speed that the vehicle would have in the bend if it underwent this maximum transverse acceleration in the presence of the detected radius of curvature, then imposing a deceleration phase on the vehicle until a deceleration speed chosen as a function of this determined maximum speed is reached.Type: GrantFiled: October 25, 2019Date of Patent: November 28, 2023Assignee: PSA AUTOMOBILES SAInventors: Claire Belle, Fabrice Perrot

Patent number: 11801813Abstract: A stably braking system and a method using the same control wheels on a single axle of a ground vehicle. Firstly, at least one of a wheel deceleration and an actual slip of each of the wheels is calculated. Hydraulic control commands are generated when a braking operation is performed in response to a braking indication signal and it is detected that the wheel deceleration or the actual slip is higher. The hydraulic control commands are configured to control a hydraulic braking system to adjust the wheel speed. When the ground vehicle drives in a straight line or turns with a first pose physical quantity, the hydraulic control command with a low priority is replaced by the hydraulic control command with a high priority and the hydraulic braking system is controlled to adjust the wheel speeds based on the identical hydraulic control commands.Type: GrantFiled: December 28, 2021Date of Patent: October 31, 2023Assignee: Automotive Research & Testing CenterInventors: Jia-Le Wei, Tsung-Hua Hsu
