Some embodiments of the present invention provide a control system configured to control a driveline of a motor vehicle to operate in a selected one of a plurality of configurations, the system being configured to receive a brake signal responsive to the application of a braking system, the system being configured to cause the driveline to operate in a second configuration and not a first configuration in dependence at least in part on the brake signal, wherein the first configuration a first group of one or more wheels and in addition a second group of one or more wheels are arranged to be driven by the driveline and in the second configuration the first group of one or more wheels and not the second group are arranged to be driven by the driveline.

Embodiments of the present invention provide a controller for a motor vehicle comprising: means for receiving information indicative of a current vehicle speed; means for receiving information indicative of an amount of brake force a braking system of the vehicle is developing or is capable of developing; means for receiving information indicative of a gradient of a driving surface on which the vehicle is driving; and torque transmission reduction means for causing a powertrain torque reduction operation to be performed in which the controller causes one or more components in a torque transmission path from a torque delivery device to driven wheels of the vehicle to assume a torque reduction condition in which torque transmission from the torque delivery device to the driven wheels is reduced or substantially terminated, the controller being configured automatically to cause the torque reduction operation to be performed in dependence at least in part on the information indicative of current vehicle speed, information indicative of brake force amount and information indicative of driving surface gradient.

A vehicle is a vehicle on which an ADK is mountable. The vehicle includes: a VP that controls the vehicle in accordance with an instruction from the ADK; and a VCIB that serves as an interface between the ADK and the VP. The VP outputs a brake pedal position signal in accordance with an amount of depression of a brake pedal by a driver, and outputs a brake pedal intervention signal, to the ADK through the VCIB. The brake pedal intervention signal indicates that the brake pedal is depressed, when the brake pedal position signal indicates that the amount of depression is larger than a threshold value, and indicates beyond autonomy deceleration of the vehicle, when a deceleration request in accordance with the amount of depression is higher than a system deceleration request.

In some examples, a controller receives information of a route of a vehicle, and selects a first parameter set from among a plurality of parameter sets based on the route of the vehicle, the plurality of parameter sets corresponding to different conditions of usage of the vehicle, where each parameter set of the plurality of parameter sets includes one or more parameters that control adjustment of one or more respective adjustable elements of the vehicle. The controller causes application of the first parameter set to control a setting of the one or more adjustable elements of the vehicle.

Devices, systems, and methods for controlling a vehicle are described. An example method for controlling a vehicle includes obtaining planning information relating to an intended operation of the vehicle over a prediction horizon; inputting the planning information into an uncertainty model to determine uncertainty information, wherein: the uncertainty model is trained using sample driving event data based on a multivariate probability prediction algorithm; and the uncertainty model is configured to predict the uncertainty information that relates to a deviation of an operation of the vehicle according to an intended control instruction from the intended operation, the intended control instruction being determined based on the planning information; generating a control instruction based on the planning information and the uncertainty information; and operating the vehicle based on the control instruction.

A system and method are provided for increasing sensitivity of a collision avoidance system of a vehicle based on driver awareness state. In one embodiment, a determination is made regarding whether or not the driver is alert based on an output of a sensor in the vehicle, such as a driver-facing camera or a sensor that detects a state of the vehicle. If the driver is found not to be alert, a lower confidence level threshold is used by a collision avoidance system of the vehicle (e.g., to more aggressively apply automatic braking). Other embodiments are provided.

A vehicle collision avoidance assistance device is configured to perform forced braking or forced steering when a driver's vehicle has a possibility of colliding with an object ahead of the driver's vehicle, acquire at least one of information related to a condition of the driver's vehicle and information related to a situation around the driver's vehicle, determine, based on the acquired information, whether a request condition for requesting execution of the forced steering is satisfied and whether a forbiddance condition for forbidding the execution of the forced steering is satisfied, perform the forced braking when the request condition is not satisfied regardless of whether the forbiddance condition is satisfied, perform the forced steering when the forbiddance condition is not satisfied and the request condition is satisfied, and perform the forced braking when the forbiddance condition is satisfied though the request condition is satisfied.

This invention relates to a vehicle speed control system, configured with off-road performance features, that will allow the driver to travel at a set speed in a smooth, controlled manner on various unmaintained surfaces without requiring the driver to press the brake or accelerator pedal. The vehicle speed control system uses a brake controller to control the wheel brakes, and an engine controller to control the engine/drivetrain torque, separate or in combination, to maintain a target speed.

A method for setting a clutch torque between an engine and a drive of a vehicle during a starting process of the vehicle includes increasing the clutch torque during a first phase, limiting the clutch torque to a first torque value during the first phase, and further increasing the clutch torque in a second phase after an engine rotational speed reaches a rotational speed limit.

A method of and system for detecting absolute acceleration along various axes relative to a desired movement vector while moving relative to a gravity source includes steps of determining a vertical acceleration, perpendicular to the desired movement vector and substantially anti-parallel to a gravitational acceleration due to the gravity source; determining a longitudinal acceleration, parallel to the desired movement vector and to output at vertical acceleration signal and a longitudinal acceleration signal; determining an inclination of the desired movement vector relative to the gravitational acceleration; and processing the vertical acceleration signal, the longitudinal acceleration signal, and the inclination signal to produce an absolute vertical acceleration signal and an absolute longitudinal acceleration signal.
