Applying braking force during shifting events involving switch-back state for a vehicle
A vehicle running control device that is provided with an accelerating-decelerating operation element with an operation range inclusive of a driving range and a braking range includes the following. An input-output section that receives various information including information on a direction in which the vehicle is currently running, a determining section that determines whether the vehicle is in a switch-back state, and an acceleration-deceleration control section that controls the vehicle running. When a braking-driving request value for an operation of the accelerating-decelerating operation element is in the braking range and the determining section determines that the vehicle is in the switch-back state, the acceleration-deceleration control section keeps the braking-driving force at a braking-driving force that is applied to the vehicle when a shift range switch request is accepted.

PROPULSION TORQUE DISTRIBUTION SYSTEM PROVIDING REMEDIAL ACTION
A propulsion torque distribution system for a vehicle includes a controller in electronic communication with a plurality of vehicle systems. The controller executes instructions to receive at least one or more computational faults, one or more sensor faults, and a driver torque request. In response to receiving at least one of the one or more computational faults and the one or more sensor faults, the controller determines a fault that affects calculation of a primary torque request has occurred. In response to determining the fault that affects calculation of the primary torque request has occurred, the controller determines a severity of the fault. The controller determines a remedial state based on the severity of the fault. The remedial state indicates a corresponding action that is executed by the propulsion torque distribution system.
METHOD FOR OPERATING A HYDRAULIC BRAKING SYSTEM, CONTROL UNIT AND BRAKING SYSTEM
The disclosure relates to a method for operating a hydraulic braking system for a motor vehicle with an electrified drive train. The braking system comprises a brake booster. First, a braking request is registered and it is determined that the braking request is to be met by pure recuperative braking. In addition, an input member of the brake booster is shifted in the direction of a pressure generation unit so that it assumes an actuation position corresponding to the braking request. From here, the input member is then shifted back from the actuation position in a direction away from the pressure generation unit for hydraulic pressure relief. A control unit designed to carry out such a method is also disclosed. A braking system comprising such a control unit is also presented.
