Systems and methods are described for controlling a vehicle braking system. An electronic controller determines a target deceleration based at least in part on a detected displacement position of a brake pedal and determines an adjusted braking pressure to be applied to at least one wheel of the vehicle such that, regardless of the displacement position of the brake pedal and the target deceleration, the adjusted braking pressure is maintained outside of a defined range of braking pressures that corresponds to a NVH condition for the at least one wheel. The adjusted braking pressure is then applied to the at least one wheel of the vehicle.

To provide a vehicle that includes a balancer mechanism for reducing vibration of the engine and can leave a space margin for increasing the fuel tank in size and/or arranging equipment or components at the rear of the cylinder and above the crankcase. A vehicle includes: an engine mounted on a body frame. The engine comprises a crankcase with a ceiling wall, a crankshaft provided in the crankcase, and a balancer mechanism for reducing vibration of the engine by power transmitted from the crankshaft. The balancer mechanism comprises an idler gear disposed behind the crankshaft and rotated by power transmitted from the crankshaft, and a first balancer disposed behind the idler gear and rotated by power transmitted from the idler gear. The idler gear and the first balancer are disposed along the ceiling wall.

A system for delivering fluid in a machine is provided. The system includes a pump, a first valve disposed downstream of the pump, a check valve disposed downstream of the first valve, at least one accumulator disposed downstream of the check valve, and an auxiliary system disposed upstream of the check valve. The system further includes a control unit configured to receive a signal indicative of a fluid demand from the auxiliary system. The control unit is also configured to selectively control the first valve in a first position to limit flow of the fluid from the pump to the auxiliary system, and in a second position to allow flow of the fluid from the pump to the auxiliary system based, at least in part, on the received signal. The check valve limits flow of a fluid from the at least one accumulator to the auxiliary system.

A method for detecting undesirable vibrations of an actuator of an electromechanical brake includes the steps of: (1) providing an electrical signal comprising at least one piece of information about a current consumption of the actuator or a parameter correlated with the current consumption; (2) monitoring an operation of the actuator on the basis of the gradient of the electrical signal in such a way that after switching on the actuator and preferably after a subsequent delay time, which includes determining: whether the amount of an initial instantaneous value of the gradient exceeds the amount of a threshold and whether a subsequent second instantaneous value of the gradient has an inverted sign compared to the first instantaneous value; (3) evaluating the results to ensure that an undesirable vibration is assessed as detected the aforementioned conditions are met.

In a hydraulic brake system, which includes: a hydraulic pump which is driven by an electric motor and has the purpose of generating a fluid volume flow for the hydraulic brake system; and a solenoid valve for controlling the fluid volume flow from the hydraulic pump to a wheel brake, a method includes actuating the solenoid valve in such a way that by this means a fluid pulsation at the wheel brake is counteracted. Furthermore, the method may be implemented in a corresponding device.

A method for operating a dual-circuit hydraulic brake system of a vehicle having an ABS function to feed back pressure medium from low-pressure reservoirs. When there is an autonomous pressure buildup request to increase brake pressure and an ABS control system is simultaneously activated, the following steps are carried out: monitoring the filling degree of the low-pressure reservoirs; emptying the low-pressure reservoir whose filling first reaches a defined threshold value; and if, during the execution of the low-pressure reservoir emptying process at the one low-pressure reservoir, the filling of the other low-pressure reservoir reaches the threshold value and the degree of emptying of the one low-pressure reservoir undershoots a defined threshold value, or the filling of the other low-pressure reservoir exceeds the threshold value by k/100, interrupting the low-pressure reservoir emptying process at the one low-pressure reservoir, and carrying out a low-pressure reservoir emptying process at the other low-pressure reservoir.

An electronic control device is provided with a hydraulic control block made of an aluminum alloy, a synthetic-resin component holder configured to hold electronic components such as a pressure sensor, and a printed board for controlling driving of hydraulic control apparatus via the component holder. Electrode terminals of the pressure sensor are connected to the printed board, a terminal configuration part of an electroconductive member, which is inserted into an insertion hole of a body wall of the component holder, is connected to a negative electrode wiring of the printed board, and the outer end edge of an elastic contact part of the electroconductive member is brought into elastic-contact with the hydraulic control block, to establish conduction therebetween. Hence, the electric potential difference between the pressure sensor and the hydraulic control block can be canceled, thus reducing an electrical noise of the pressure sensor.
