Disclosed herein an electric parking brake (EPB) system includes an EPB configured to provide a clamping force to a vehicle for parking; and a controller configured to engage the EPB; wherein the controller is configured to determine whether the vehicle is in an early stage of vehicle release or an early stage of brake pad replacement based on a driving distance and brake pad replacement information of the vehicle during a parking operation, and upon determining that the vehicle is in the early stages of vehicle release or brake pad replacement, compensate for a target clamping force of the EPB and perform the parking operation based on the compensated target clamping force.

A method for diagnosing whether or not a judder detection module mounted on a vehicle is operating normally includes receiving a diagnosis request requesting that the judder detection module of the vehicle be diagnosed; preparing for an execution environment for diagnosis of the judder detection module; activating the judder detection module; forcibly generating judder in the vehicle; and determining whether or not the judder detection module operates.

A towing device operably provided on a trailer for powering and controlling the trailer. The towing device has an actuator operably connected with the trailer during a towing operation. The towing device also has at least one switch provided in the actuator and operable to variably control at least one motor/generator provided on the trailer. The at least one switch is also operable to send a first signal to the at least one motor/generator via a first force exerted on the actuator by a vehicle, and wherein a first torque is applied to at least one wheel on the trailer via the at least one motor/generator being operably engaged with the at least one wheel. In addition, the towing device may include a controller operably connected to the at least one switch and to the at least one motor/generator, to control the torque applied by the at least one motor/generator.

The invention provides a locking device for preventing movement between two elements (11, 12) that are mounted to move relative to each other, the locking device including a lock (31) mounted to rotate relative to one of the elements in order to present successive angular positions for locking and for release in which the lock alternates between preventing and allowing relative movement between the two elements, the lock being constrained to rotate with a selector (55) of an angular indexing mechanism (50) actuated by a pulse-controlled actuator (70, 71) arranged to push the selector against a spring member (58) in order to cause it to turn on each pulse and thereby cause the lock to pass from one angular position to the other.

Provided is a vehicle braking control device applicable to a vehicle equipped with an electric-powered parking braking device, a hydraulic braking device and a regenerative braking device. The braking control device comprises a first braking control unit and a second braking control unit. When a parking braking operation is performed while the vehicle is travelling, the first braking control unit implements a first braking process which increases the braking force to the vehicle by operating the hydraulic braking device. When the braking force to the vehicle needs to be increased in a situation where the first braking process is being implemented, the second braking control unit implements a second braking process which increases the braking force to the vehicle by operating the regenerative braking device.

A straddled vehicle has a plurality of modes for engine brake controlling. The straddle vehicle includes a mode setter that selectively sets one of at least a normal mode and a first reduced mode that are included in the plurality of modes. An engine controller controls an electronic throttle valve and a fuel injector so that a torque of an internal combustion engine is equal to a target torque. When the torque of the internal combustion engine is less than zero while in the first reduced mode, an engine brake controller corrects the target torque by adding a first additive torque to the target torque. The first additive torque is set so as to be smaller as an amount of operation of an accelerator grip becomes larger so that an opening of the electronic throttle valve increases as the amount of operation of the accelerator grip increases.

An electropneumatic brake system, for a commercial vehicle which is provided for pulling a trailer, includes at least one service brake circuit configured to activate service brake actuators, a parking brake circuit having parking brake actuators on at least one axle, a trailer brake circuit configured to provide a trailer brake pressure at a trailer brake pressure port, and a manually actuatable operating unit in a driver's cab. The manually actuatable operating unit has a first operating element and a second operating element. In the case of actuation of the first operating element when the vehicle is driving, the parking brake actuators are activated and a trailer brake pressure is output at the trailer brake pressure port. In the case of actuation of the second operating element when the vehicle is driving, only a trailer brake pressure is output.

A method for operating an accelerator pedal-controlled distance controller of a vehicle. The distance controller regulates a distance to a target vehicle as a function of an actuator pedal value of the vehicle and activates automatic braking operations as necessary. A braking operation is aborted when the accelerator pedal value is increased during the braking operation.
