Anti-lock brake system for all-terrain vehicle
An all-terrain vehicle is disclosed having a braking system with an anti-lock braking control module and a first brake master cylinder hydraulically coupled to the anti-lock braking control module. A first brake actuator is coupled to the first brake master cylinder and a brake caliper is coupled to at least some of the ground engaging members. The first brake master cylinder upon actuation provides anti-lock braking to either the first or second ground engaging members. A second brake master cylinder is hydraulically coupled to the anti-lock braking control module. A second brake actuator is coupled to the second brake master cylinder and a brake caliper is coupled to at least some of the ground engaging members. The second brake master cylinder upon actuation provides anti-lock braking to either the first or second ground engaging members. The vehicle also has a speed monitor with a gear ring positioned on an exterior surface of a stub shaft and a speed pickup positioned adjacent to the gear ring.
Regenerative braking control system
A vehicle includes an electric machine, friction brakes, and a controller. The electric machine is configured to recharge a battery during regenerative braking. The friction brakes are configured to apply torque to wheels of the vehicle to decelerate the vehicle. The controller is programmed to, responsive to an anti-lock braking event, adjust a regenerative braking torque of the electric machine based on a difference between a desired wheel slip ratio and an actual wheel slip ratio.
Method for controlling brakes in a trailer vehicle
Disclosed is a method for controlling brakes in a trailer vehicle comprising a pneumatic brake system, service brakes and an electronic brake system with anti-lock control, wherein at least one axle of the trailer vehicle is fitted with spring-loaded brakes and revolution rate sensors. The method comprises: monitoring with the electronic brake system whether there is a braking demand, monitoring with the electronic brake system whether at least one wheel of at least one axle is locking up, and if there is no braking demand and at least one wheel of the at least one axle is locked while traveling, controlling the pneumatic braking system with the electronic brake system to pressurize the spring-loaded brakes and to brake the trailer vehicle by the service brakes automatically and with anti-lock control. A valve arrangement is also disclosed.
Variable-torque emergency brake device
An emergency braking device including an actuator (2), a pressurizing circuit (3) supplying the actuator (2) via a control pressure and a discharge circuit (4). The discharge circuit (4) includes restrictors (13, 14) for controlling the pressure and/or flow rate of the supply fluid of the actuator (2) during a discharge of the actuator. The restrictors (13, 14) are configured to define an intermediate pressure between a low pressure level and the control pressure of the actuator (2).
METHOD AND CONTROL UNIT FOR CONTROLLING A HYDRAULIC BRAKING SYSTEM
A method for controlling a hydraulic braking system of a vehicle. The braking system includes a controllable first braking pressure generator and a sensor for a deceleration signal of the vehicle. The method includes: impressing a pressure characteristic with the aid of the first braking pressure generator on an original setpoint braking pressure; and monitoring the deceleration signal for the presence of a deceleration characteristic corresponding to the pressure characteristic.
BRAKE APPARATUS, CONTROL APPARATUS FOR VEHICLE, AND ELECTRIC BRAKE CONTROL APPARATUS
A brake apparatus including a hydraulic brake mechanism, an electric brake mechanism, and first and second controllers. The hydraulic brake mechanism can apply a braking force by thrusting a braking member forward with use of hydraulic pressure to a wheel belonging to a first group among a plurality of wheels of the vehicle. The electric brake mechanism can apply a braking force by thrusting a braking member forward with use of an electric motor to a wheel belonging to a second group among the plurality of wheels. The first controller can control the hydraulic brake mechanism, and the second controller can control the electric brake mechanism. The first controller acquires or receives at least one of yaw rate information of the vehicle and acceleration information of the vehicle without intervention of the second controller. The second controller acquires or receives wheel speed information without intervention of the first controller.
CONTROLLER AND CONTROL METHOD FOR VEHICLE
A controller for a vehicle is provided. One of a prime mover that drives a front wheel and a prime mover that drives a rear wheel is referred to as a first prime mover, and the other one is referred to as a second prime mover. The controller generates, when a required torque required for a drive wheel of the vehicle is a braking torque, the braking torque from the first prime mover. The controller limits, when the required torque changes from the braking torque to a driving torque, an increase in the driving torque generated from the first prime mover during a set period. The controller generates, from the second prime mover that does not generate the braking torque, the driving torque required during execution of the torque limit process.
BRAKING DEVICE FOR A WORKING MACHINE
The invention relates to a braking device for a work machine comprising a pressure supply, a brake circuit, at least one brake actuable via the brake circuit, a manually controllable brake valve by means of which the brake circuit is actuable, a control unit, and at least one control valve that is controllable by the control unit and by means of which the brake circuit is actuable. In accordance with the invention, the total brake torque exerted by the at least one brake is adjustable by means of a corresponding control or regulation of the at least one control valve in dependence on at least two input signals detectable by the control unit, with a first input signal relating to a current state of the manual actuation of the brake valve and a second input signal relating to a current driving state of the work machine
