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.

A method determines a roadway condition using steering actuators, wherein at least two steering actuators are arranged on each vehicle wheel. Measurement variables of the first and second steering actuators are sensed. The sensed measurement variables of the two steering actuators are compared with one another and, an inhomogeneity signal is determined from the deviation between the sensed measurement variables of the two steering actuators. If the inhomogeneity signal lies within a tolerance range, a homogeneous roadway condition exists. If the inhomogeneity signal lies outside the tolerance range, an inhomogeneous roadway condition exists.

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 redundant control system is applied to a brake-by-wire (BBW) system. The redundant control system applied to the BBW system includes electromechanical brakes (EMBs) provided at wheels of a vehicle and configured to perform brake control of the vehicle, controllers connected to the EMBs, respectively, and a local gateway on a first communication line configured to receive information on the vehicle and a command of a driver and to transmit the information on the vehicle and the command of the driver to the controllers, where the controllers are configured to receive the information on the vehicle and the command of the driver through a second communication line.

A system includes a controller configured to individually control brake force applied to steered wheels of a vehicle. The controller is configured to release a braking force from a first brake associated with a first steered wheel of the vehicle when the vehicle is stationary, and the controller is further configured to subsequently release a braking force from a second brake of a second steered wheel when the vehicle remains stationary after braking force is released from the first wheel. Methods relate to distributing braking force of a vehicle.

Motorcycles can become unstable when operating at high speeds and at high cornering levels. For example, they can exhibit an oscillation at the rear wheel commonly known as “weave.” A system and method is provided which utilizes a high-fidelity computer simulation model of a 2- or 3-wheel motorcycle to predict operating states such as yaw rate, lateral acceleration and roll angle for a stable motorcycle at a given speed and steer angle. The operating state of a physical motorcycle can be measured and compared to that of the model at every instant in time to determine if the operating state of the physical motorcycle differs from that of the simulation model in such a way as to indicate loss of stability. The nature of that difference can then be used to intervene in the operation of the motorcycle independent of driver actions by application of brakes, modulating the engine torque or applying torques to urge the steering system in a corrective direction. Thus by comparing the physical response of the motorcycle to that of the computer model in an on-board controller these interventions can be applied at a time and intensity to stabilize the motorcycle and prevent a loss of control.

A motorised vehicle comprises a first wheel located laterally on a first side of the vehicle, and a second wheel located laterally on a second side of the vehicle opposite the first side. The vehicle comprises a steering system configured to modify the orientation of the wheels and to turn the vehicle. The vehicle comprises a trajectory modifier configured to vary the speed of rotation of the first wheel and to modify the trajectory of the vehicle in the event of failure of the steering system.

A braking system and a method of operating such a braking system are provided for a vehicle having at least partly electric braking, a steering device containing an electric or electromechanical steering device, an electronic steering controller and an electric steering adjuster and containing a service brake device. The system includes an electropneumatic service brake device containing an electropneumatic service brake valve device, an electronic brake controller, electropneumatic modulators, pneumatic wheel brake actuators, a service brake actuating element, and at least one electric channel (130) with at least one electric brake value transmitter which senses activation of the service brake actuating element. The at least one electric brake value transmitter produces actuation signals which are relayed to the electronic brake controller. The electronic brake controller causes a first actuation force to be applied to at least one control piston of the service brake valve device to control at least one double seat valve of the service brake valve device to generate pneumatic braking pressures or brake control pressures for the pneumatic wheel brake actuators. The electronic controls are further configured to generate a second actuation force on the at least one control piston when a brake request independent of the driver's request exists, independent of a driver brake request. The electropneumatic service brake device is supplied with energy independently from energy supplied to the electropneumatic service brake valve device and the electric or electromechanical steering device.
