A system and method are provided for disabling a retarder during a gearshift at low speeds for improved driver comfort. These embodiments recognize that power flow is interrupted during a shifting process and use that opportunity to disable the retarder at low speeds, thereby eliminating an additional, uncomfortable jolt to the driver. Several embodiments are provided.

This control device for a vehicle switches a shift range of an automatic transmission through the use of an actuator, wherein the control device for a vehicle is characterized in being provided with a shift selection unit for receiving a shift position selection from a driver and a control unit for switching the shift range to a parking range through the use of an actuator when a vehicle power source turns off or when a drive power source stops, the control unit maintaining a neutral range, when the vehicle power source turns off or when the drive power source stops, until the elapse of a first prescribed time after the shift selection unit receives a neutral position selection while the vehicle power source is on or while the drive power source is driving.

A vehicle includes a fault-tolerant braking system that controls a brake assembly which is configured to adjust a braking force applied to one or more wheels. The fault-tolerant braking system further includes a brake-by-wire (BBW) system and a vehicle control module (VCM). The BBW system is configured to control the brake assembly in response to a braking request. The VCM is configured to detect a fault of at least one of the brake assembly and the BBW system. In response to detecting the fault, the VCM selectively operates the vehicle between a normal operating mode and at least one degraded driving mode that limits operation of at least one of the vehicle engine and the vehicle transmission compared to the normal operating mode.

A driving control apparatus for a vehicle is disclosed. The driving control apparatus includes: an object detection device configured to detect objects in the vicinity of the vehicle and generate information on the objects; a sensing unit configured to detect a state of the vehicle and generate vehicle state information; and a processor configured to: based on the vehicle state information and the information on the objects, generate information on collision with a first object out of the objects, and based on the information on the collision, generate a control signal for at least one of steering, partial braking, and partial driving of the vehicle and provide the generated control signal so as to control operation of the vehicle after the collision through at least one of a steering control action, a partial braking control action, and a partial driving control action.
