The present invention relates to a method for collision avoidance for a host vehicle, the method comprising: detecting a target in the vicinity of the vehicle; determining that the host vehicle is travelling on a collision course with the target; detecting a user initiated steering action for steering the vehicle towards one side of the target; determining a degree of understeering of the host vehicle; when the degree of understeering exceeds a first understeering threshold, controlling a steering control system of the vehicle to counteract the user initiated steering action to thereby reduce the degree of understeering. The invention further relates to an evasive steering system.

The invention relates to a method of controlling a heavy-duty vehicle in a slope when the vehicle has come to a standstill due to service brakes of the vehicle having applied a service brake force, the method comprising determining a total brake force required for maintaining the vehicle at standstill, activating at least one park brake for providing a park brake force, gradually increasing the park brake force, and, while the park brake force is gradually increased, gradually reducing the service brake force while maintaining the sum of the service brake force and the park brake force at least equal to the determined total brake force.

A control device is for controlling an autonomous motor vehicle in order to modify a steering angle of a steered wheel of the autonomous motor vehicle and/or a braking force generated by the brake fitted to a wheel of the autonomous motor vehicle. The control device includes an automatic piloting system, which is configured to generate an automatic driving instruction for automatically driving the vehicle, a primary command chain, which includes a primary controller configured to generate a primary command according to the automatic driving instruction, and at least one primary actuator configured to generate a torque that confers a steering angle to the steered wheel, or configured to actuate the brake based on the primary command obtained directly from the primary controller. A secondary command chain is also included.

A method for controlling a vehicle driveline includes determining, for current vehicle operating conditions, an initial engine output torque, at which the driveline meets predetermined structural criteria, establishing a factor that varies with torque converter slip, determining an engine torque limit by multiplying the factor corresponding to a current torque converter slip by the initial engine output torque, and limiting torque produced by an engine connected to the driveline to the engine torque limit.

A control unit for controlling an upstream braking actuator for generating upstream pressure and a downstream braking actuator for controlling braking pressures of four wheels using the upstream pressure is configured to, when a braking pressure of any wheel cannot be reduced, perform backup control so that the target upstream pressure becomes the target braking pressure of the relevant wheel, and is configured to, when performing anti-skid control in a situation where automatic braking and backup control are being performed, control the target upstream pressure such that the target upstream pressure becomes a target upstream pressure for the automatic braking when the target upstream pressure is the target braking pressure for the relevant wheel, and such that the target upstream pressure becomes the target braking pressure for the anti-skid of the relevant wheel when the target upstream pressure is not the target braking pressure of the relevant wheel.

A vehicle control apparatus is mounted to an own vehicle and controls the own vehicle such that an inter-vehicle distance between a preceding vehicle and the own vehicle becomes a reference distance. The vehicle control apparatus acquires passing suitability information indicating whether or not the own vehicle is able to pass the preceding vehicle. When the own vehicle is not able to pass the preceding vehicle, the vehicle control apparatus corrects the inter-vehicle distance by adding a correction distance to a reference distance.

A braking system includes a brake pipe, a pressure sensor and a pressure valve, each operatively associated with the brake pipe. The pressure valve is directed to reduce a pressure in the brake pipe in response to data from the pressure sensor, and a secondary pressure sensor is operatively associated with the brake pipe, wherein a pressure in the brake pipe is reduced in to data from the secondary pressure sensor.
