A differentially steered vehicle includes brakes on the powered wheels which are applied via a controller according to different methods to inhibit freewheeling during turns and improve steering responsiveness and stability. The methods include applying braking force to the wheel on the inside of a turn in response to the rate of turn as indicated by the position of the steering control, to the pressure differential across the hydraulic motors driving the wheels and the rotational speed of the wheels.

A vehicle control system includes: a first device that generates trajectory data indicating a future trajectory of a host vehicle and outputs the generated trajectory data; a second device that controls at least one of acceleration/deceleration and steering of the host vehicle on the basis of the trajectory data generated by the first device; and a third device that receives the trajectory data generated by the first device and writes the received trajectory data in a storage unit thereof, the third device being a device separate from at least the first device, wherein when an abnormality occurs in the trajectory data output by the first device, the second device controls at least one of acceleration/deceleration and steering of the host vehicle on the basis of the trajectory data which has been received by the third device and written in the storage unit before the abnormality occurred.

A vehicle control apparatus includes a time-to-collision acquisition unit that acquires time to collision that is a time period until a time of collision of an own vehicle with a front obstacle, an overlap rate acquisition unit that acquires an overlap rate indicating a relative positional relationship between the own vehicle and the front obstacle in a lateral direction perpendicular to a traveling direction of the own vehicle, a determination unit that performs execution determination of automatic braking control of the own vehicle, on the basis of the time to collision and the overlap rate, and that, when the overlap rate is increasing by the front obstacle approaching the own vehicle in the lateral direction, determines start timing of the automatic braking control as earlier timing than when the overlap rate is not increasing, and an automatic controller that executes the automatic braking control at the start timing.

A safety stoppage device for an autonomous road vehicle having at least one control network and sensor, and an autonomous drive-control unit for processing sensor and communication signals and providing control signals for lateral and longitudinal control. A primary brake-control unit is configured to monitor the longitudinal control signals for faults and, upon determination of a fault, execute a longitudinal control profile, stored independent from the autonomous drive-control unit, to perform braking to a stop. A primary steering-control unit is configured to monitor the lateral control signals for faults and, upon determination of a fault, control a primary steering actuator to follow a lateral control trajectory, stored independent from the autonomous drive-control unit, and, if not already triggered, simultaneously trigger the primary brake-control unit to execute the stored longitudinal control profile to control wheel brakes to perform braking to a stop during execution of the lateral control trajectory.

A vehicle control device to be installed in a vehicle includes a self-driving controller and a calculator. The self-driving controller is configured to set a target vehicle speed and a target steering angle to allow the vehicle to trace a predetermined target travel locus. The self-driving controller is configured to control the vehicle based on the target vehicle speed and the target steering angle. The calculator is configured to calculate a deviation between an index of an actual vehicle behavior and an index of a reference vehicle behavior. The self-driving controller corrects one or both of the target vehicle speed and the target steering angle in accordance with an increase of the deviation, so as to stabilize the vehicle.

An over actuated system capable of controlling wheel parameters, such as speed (e.g., by torque and braking), steering angles, caster angles, camber angles, and toe angles, of wheels in an associated vehicle. The system may determine the associated vehicle is in a rollover state and adjust wheel parameters to prevent vehicle rollover. Additionally, the system may determine a driving state and dynamically adjust wheel parameters to optimize driving, including, for example, cornering and parking. Such a system may also dynamically detect wheel misalignment and provide alignment and/or corrective driving solutions. Further, by utilizing degenerate solutions for driving, the system may also estimate tire-surface parameterization data for various road surfaces and make such estimates available for other vehicles via a network.

A method includes ascertaining that an emergency braking operation of a single-track motor vehicle is to be automatically executed driver independently, and based on the ascertainment, automatically and driver-independently influencing a steering element of the motor vehicle during the execution of the emergency braking operation.

A braking system for vehicles may have a control unit for two brake groups operatively connected to electromechanical actuators for each brake group through a relative piloting device. Each control unit may be powered by a power source and being galvanically isolated from other power sources. Each control unit may be programmed to implement, via a piloting device, a standard braking strategy in case of detection of a standard operation of each brake group and a fault braking strategy, if it detects an electrical fault of one or more of the brake groups.

A vehicle system includes a steering wheel configured to output an output based on an input from a user, and a controller configured to: determine a target orientation of front wheels of a vehicle based on vehicle environment information, determine whether an orientation of the front wheels of the vehicle based on the output from the steering wheel deviates from the target orientation, disengage the steering wheel from the front wheels in response to determination that the orientation of the front wheels deviates from the target orientation, adjust the orientation of the front wheels to the target orientation and provide a feedback in response to adjusting the orientation of the front wheels to the target orientation.

A redundant mechatronic system. The redundant mechatronic system is formed with two channels and is or can be connected for the output of a varying mechanical power to a mechanical arrangement, wherein each of the two channels includes an energy supply and an actuation circuit or a common energy supply is connected upstream of both channels, and both channels can be controlled by at least one control unit. The control unit acts on the actuation circuits in such a manner that the actuation circuits in each case switch an electric power specified by the control unit and drawn from the energy supply through to in each case a winding set of at least one electrically operated actuator, in order to generate the mechanical power. The two channels are operated in parallel during normal operation, in such a manner that each channel provides half of the mechanical power to be instantaneously output.
