A controller that controls behavior of a vehicle, and includes a control section that controls deceleration of the vehicle. In a situation where the vehicle is being decelerated, when a shift position of the vehicle is switched from a first position, at which power can be transmitted between a drive source (for example, an engine and a travel motor) of the vehicle and a drive wheel of the vehicle, to a second position, at which the power cannot be transmitted between the drive source and the drive wheel in an unlocked state of the drive wheel, the control section executes automatic deceleration control for automatically increasing the deceleration of the vehicle with respect to deceleration depending on a brake operation by the driver of the vehicle.

Provided is a work vehicle capable of satisfying a user's demand to brake performance in a flexible manner. A wheel loader 1 comprises a controller 5 storing a plurality of control characteristics each of which is set such that a brake valve control pressure Pi of a solenoid proportional valve 45 increases as a pedal angle of a brake pedal 43 increases, and under the condition where a pedal angle is equal to or less than a predetermined pedal angle , an increase rate of the brake valve control pressure Pi with respect to the pedal angle varies. In a case where the pedal angle detected by a potentiometer 33 is equal to or less than the predetermined pedal angle th, the controller 5, calculates the brake valve control pressure Pi based on the selected one control characteristic.

A number of illustrative variations may include a system that may manage torque overlay scenarios in a vehicle where the brakes and propulsion system are providing both lateral and longitudinal movement commands and there is a change in longitudinal acceleration requested from a driver or autonomous driving system.

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 vehicle brake system for giving an excellent brake feeling to a driver includes: a stroke detector configured to detect a stroke of a brake pedal; a brake fluid pressure generator including a motor actuator and configured to generate a brake fluid pressure by operation of the motor actuator, and a controller configured to control the operation of the motor actuator on the basis of a detected value by the stroke detector.

A proximity detection system for detecting motion and proximity of an occupant seated in a vehicle. The system includes a sensing electrode located proximate to the occupant and configured to transmit a signal representative of a current in the sensing electrode. The system includes a receiver including a controller and coupled to an antenna. The receiver is configured to detect a change in the transmitted signal received by the antenna based on the proximity of the occupant. The receiver is configured to determine the presence of the occupant based on the amplitude of the signal received by the antenna and the rate change of the amplitude of the signal received by the antenna. The receiver is configured to generate a control signal to change a state of a vehicle component when at least one of the amplitude and the rate of change of the amplitude exceed a predetermined threshold.

A brake system includes a brake activator which first activates a central rear brake and lastly activates a front brake of a right front brake and a left front brake which is provided on a front wheel which is an inner wheel by operating an input member. When an operation amount of the input member from an initial state to a maximum operated state thereof is divided equally into three portions which are defined as a low braking force area, a middle braking force area, and a high braking force area, the brake activator activates the central rear brake, the right front brake, and the left front brake to operate in the low braking force area.

A displacement sensor includes a resistive element and a wiper element. The wiper element is separated from the resistive element in a parked mode the wiper element is in sliding electrical contact with the resistive element in a sensing mode. A user input interface may be coupled to at least one of the resistive element and the wiper element, wherein whether the displacement sensor is in the parked mode or the sensing mode is dependent on actuation of the user input interface.

Provided is an electric booster capable of detecting a movement position of an input member in a wide range along an axial direction. The electric booster includes an input rod formed of a magnetic material, an input plunger formed of a non-magnetic material, and an input piston formed of a magnetic material. A stroke detector includes respective magnet members arranged so that magnetic poles are aligned along a movement direction of the input plunger, and a Hall sensor unit that is fixed to a housing, and detects a movement position of the input plunger in accordance with a magnetic flux density from the respective magnet members. As a result, a flat magnetic flux distribution having a wide region along the axial direction is provided, and the movement position of the input plunger can be detected relatively precisely in a wide range along the axial direction.
