A stroke sensing apparatus for a brake pedal includes a pedal rod moved by an operation of the brake pedal; a magnet part mounted on the pedal rod and moved together with the pedal rod; a sensor spaced apart from the magnet part; a printed circuit board (PCB) part on which the sensor is mounted; and a pole piece part mounted on the PCB, spaced apart from the magnet part, and transmitting a magnetic field change generated in the magnet part to the sensor.

A wheel chock system. In one aspect of the invention, an actuator is configured to move a pair of wheel chocks to an activated position in which motion of the wheel is prevented. A control unit controls the actuator and, based upon determination that a plurality of predefined conditions are met, the control unit may after having received an operator-initiated activation request, cause the actuator to move the wheel chocks from the inactivated position to the activated position. In another aspect of the invention, the actuator comprises a bi-directional motor and a gear mechanism, for moving the wheel chocks to the activated position. The invention also relates to a vehicle comprising a wheel chock system.

An automatic braking system for a vehicle includes a sensor system configured to detect the previous speed of the vehicle, occupancy of a driver's seat of the vehicle, and an input to at least one of an accelerator pedal of the vehicle and a brake pedal of the vehicle. The automatic braking system also includes a control module communicatively connected to the sensor system and configured to automatically brake the vehicle when the vehicle was previously stopped, the driver's seat is occupied, and there is no input to the accelerator pedal or the brake pedal.

The disclosed vehicle braking device controls a hydraulic brake system (2) and a regeneration brake system (3) mounted on a vehicle (1) in accordance with an acceleration value and a brake value, and includes a first divider (11), a second divider (12), and a controller (13). The first divider (11) divides a driver demand torque set according to the accelerator value into a target coast torque and a remaining torque. The second divider (12) divides a sum of a deceleration torque set according to the brake value and the target coast torque divided by the first divider (11) into a hydraulic-brake demand torque and a regeneration-brake demand torque. The controller (13) controls the hydraulic brake system (2), using the hydraulic-brake demand torque, and controls the regeneration brake system (3), using a total regeneration brake torque calculated from the remaining torque and the regeneration-brake demand torque. This configuration can improve the feeling of operating the brake, resolving the feeling of the shortage of deceleration.

An electric motor-driven brake device for use in a wheeled vehicle is provided with low costs which appropriately enables the wheeled vehicle running and stopping as it usually does, even when a malfunction and/or abnormality are/is caused in the electric motor-driven brake device. Signal lines of stroke sensors each for detecting the quantity of stroke of a brake pedal are connected to controllers in an electric motor-drive unit for controlling a motor which drives an electric motor-driven piston of a brake pad(s) attached thereat.

Monitoring the brake performance of a brake system of a machine (vehicle 11) by determining a brake delay between input of a request for a brake engagement of the brake system and brake system effectuating the brake engagement. The brake delay determination provides for capturing delay produced by communication of the input from a brake input, actuation of an input to brake system performance, processing of operation of the brake system, and operation of the brake/retardation components of the brake system with respect to the machine's wheels. For autonomous machines, brake delay may be measured periodically and used in monitoring brake system performance.

A controller and a control method to a vehicle, the controller and the control method executing brake control in which primary information is selectively supplemented by secondary information that is information on an assumed state related to connection and disconnection of a clutch. The controller includes a determination section that determines whether an actual state and the assumed state, which are related to the connection and the disconnection of the clutch, match each other in accordance with a temporal change in the secondary information; and a brake control section that executes the brake control by using the primary information but not the secondary information in the case where the determination section determines that the actual state and the assumed state do not match each other.

In a method for monitoring the operational reliability of a braking system in a vehicle. A brake pedal actuation is monitored via a brake light switch. An error signal is generated if the brake light switch generates a switch signal, without a braking intent of the driver being registered via a sensor signal of a sensor.

A system for controlling actuators based on pedal positions in a vehicle is described. The system comprises a control unit and a camera. The camera is configured to capture an image containing two or more pedals in a vehicle and to provide the image to the control unit. The control unit is configured to determine for each pedal, based on the provided image, the current position of the pedal relative to a fixed structure in the vehicle or relative to a reference position of the pedal, and control, based on the determined position, an actuator associated with the pedal.
