R90 is a system that does not allow gear vehicles to go back without the driver's discretion. R90 also takes the brake pedal when the deviation is more than ninety degrees, while vehicle is out of the driver's control and the vehicle bottom moves forward from its head.

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.

A method for driving a parking brake of a vehicle (V) wherein: for a setpoint between 0 and C1, the control pressure (200) is zero, and the supplementary pressure (100) is nonzero constant; for a setpoint between C1 and C3, the control pressure is proportional to the setpoint, for a setpoint between C2 and Cmax, the supplementary pressure is zero;
said values being such that

0<C1<C2<Cmax, and

0<C1<C3<Cmax.

A method for detecting malfunctions of a motor vehicle electro-actuated brake apparatus may include the steps of providing, in an electronic control unit, a functional control block and a first functional block having a numerical model representative of the electro-actuated brake caliper. The method may also include providing a target signal to the functional control block for generating the control signal to operate the electro-actuated brake caliper. The method may also include providing the target signal to the first functional block for generating a first signal. In the method, the first signal may be compared with a feedback signal for generating an error signal to be sent to the electronic control unit. Further, the method may include performing, by the second functional block, an error validation check to provide information on the operating state of the electro-actuated brake caliper to the electronic control unit.

A pedal device includes a base disposed on an inner wall surface of a vehicle body, a pedal pad movable relative to the base, and a pad fixation portion configured to fix the pedal pad to be immovable relative to the base.

A park brake system for adjusting a tension in a brake cable that is coupled to a park brake. The park brake system can include a driver that is communicatively coupled to a microcontroller, and an actuator that is rotatably displaceable by operation of the driver. An equalizer assembly can be linearly displaced along the rotating actuator to adjust a tension in the brake cable. The microcontroller can monitor a current being drawn by the driver as the driver is operated, and generate instructions to cease operation of the driver upon the current reaching a predetermined current threshold that corresponds a maximum force that is to be applied by the park brake. The microcontroller can also, when the park brake is being released from a set position, count pulses outputted by an encoder in connection with determining whether the park brake has reached a running clearance position.

The present invention relates to a construction machine, said construction machine comprising a brake assembly for braking the machine, as well as an operator platform. The operator platform comprises at least one operator seat with a total of at least two operating positions for a machine operator at opposite ends of the operator platform, and an actuation device for foot actuation of the brake assembly. According to essential aspects of the present invention, the actuation device for the brake assembly comprises a brake beam which extends transversely to the working direction of the construction machine and which can be operated by foot from said two operating positions, and the actuation device further comprises an actuator for the brake beam, which is arranged below the brake beam.

The invention relates to a method and an arrangement for controlling a vehicle (100) during a downhill start. The vehicle comprises a service brake (131a, 131b; 132a, 132b; 33a, 133b), an engine (119) and a transmission (120) being arranged between the engine and at least one driven axle (123), wherein the service brakes, the engine and the transmission are controlled by an electronic control unit (140). The method involves registering that the vehicle is located on a downhill gradient; registering an action from the driver, indicating a request to start the vehicle; controlling the service brake to maintain the vehicle stationary during a predetermined time after the request before initiating a controlled service brake release; controlling a gradual release of the service brake in response to at least one detected first vehicle operating parameter; and releasing the service brake when detecting that a predetermined threshold for at least one second vehicle operating parameter has been attained.

A brake control device is a control device for a vehicle used in a vehicle on which the shift-by-wire system and the brake-by-wire system are mounted. A function of automatically operating the brake device without an operation of the driver of the vehicle is referred to as a BBW automatic operation function, and a request by the driver for disabling the BBW automatic operation function is referred to as a disabling request. A brake control device includes a disabling determination part configured to determine a presence or absence of the disabling request, the vehicle stop determination part configured to determine whether the vehicle is stopped, a slope determination part configured to determine whether the vehicle is located on a slope, and a BBW automatic operation part. The BBW automatic operation part operates the brake device when the vehicle is stopped on the slope even if the disabling request is made.

A riding mower includes a seat, a main rack configured to bear the seat, a mowing element, a walking assembly for enabling the riding mower to walk across a lawn, and an operation assembly configured to be operated by the user so that the riding mower is controlled to walk and output power. The riding mower further includes a parking system, a linkage mechanism and a gearbox. The parking system is configured to switch the riding mower between a parking state and a non-parking state. The linkage mechanism is connected to the parking system. The gearbox is connected to the linkage mechanism. The parking system controls, through the linkage mechanism, the gearbox to implement braking.
