An angle detection apparatus includes a magnetic detection element, a magnetic field generator, and a first magnetic shield. The magnetic field generator is magnetized along a first direction and generates a magnetic field to be applied to the magnetic detection element. The first magnetic shield surrounds the magnetic detection element along a plane orthogonal to the first direction. The magnetic field generator and the magnetic detection element are rotatable relative to each other around a rotation axis along the first direction.

Towed vehicles can be extremely heavy. Accordingly, it is too much of a burden to the braking system of a towing vehicle to not have brakes on the towed vehicle. Controlling the brakes of the towed vehicle must be accurately applied otherwise undesirable conditions can be created. There is a need for a method for controlling braking of a towed vehicle. This method comprises receiving a first signal via a communication bus of a towing vehicle, the first signal relating to at least one operating condition of at least one the towing vehicle and a towed vehicle, sending a second signal to brakes of the towed vehicle, the second signal based on said first signal.

An assistance System for a vehicle for providing an emergency stop assistance function that includes an execution device to execute the emergency stop assistance function using at least one of a plurality of activation stages; a detection device for automatic detection of driver inactivity, in order to activate the emergency stop assistance function using a first stage selection of the activation stages; a triggering device for monitoring an operating element of an electrical parking brake or a parking lock of a transmission of the vehicle, in order to activate the emergency assistance function using a second stage selection of the activation stages, which differs from the first stage selection, in the case of a manual activation of the operating element.

A method is provided for wireless communication between a wireless remote control device comprising a peripheral device and a controller on a materials handling vehicle comprising a central device. The method may comprise: polling via a plurality of connection event requests, by the central device, communicated with the peripheral device with which the central device is paired, the peripheral device comprising one or more activatable switches. Based on the status of one or more activatable switches, the peripheral device sending reply messages to at least a portion of the plurality of connection requests in accordance with at least one communication operating mode of the peripheral device, wherein each reply message is indicative of the status of the one or more activatable switches. Calculating, by the central device, a number of missed messages.

A drum brake module for motor vehicles, the drum brake module being driven by an electric motor and having at least one parking brake function, includes an electromechanical cable pull actuator which is fastened on the anchor plate with the aid of an adapter. The adapter is designed as a one-piece, thin walled frame having at least one fastening flange for receiving the cable pull actuator and is held in place on the anchor plate.

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.

A system and method for operating a motor vehicle with an electric parking brake. The system includes a clutch sensor, generating a clutch sensor signal representing operation of a clutch of the motor vehicle. A gear selection sensor generates a sensor signal indicating a particular gear selection or position of a manual gearbox of the motor vehicle. Using these and if needed other various inputs, the system generates a deactivation signal for releasing the electric parking brake when a clutch operation is detected and the vehicle gearbox is positioned or has a gear selection other than a neutral position of the manual gearbox.

One embodiment of a braking system for vehicles may have a first brake group and a second brake group. The first and second brake groups may have respective braking devices and electro-hydraulic actuator devices operatively connected to the first braking device. The system may also have an interconnection branch between first and the second hydraulic actuation ducts, provided with a control valve. The system may also have at least one control unit that may be programmed to actuate the control valve to control the ducts and fluidly connect the ducts.

A commercial vehicle with at least one driven axle, at least one service brake, at least one propulsion engine, and wheels characterized in that the parking brake function of the vehicle is solved by a bistable locking means acting on both wheels. At least one multi-speed gearbox is provided to concurrently activate a first gear stage and a second gear stage having different ratios.
