A vehicle includes a chassis, a power system supported by the chassis, and a plurality of wheels supported by the chassis. At least one of the plurality of wheels is operatively connected to the power system. A plurality of brakes is operatively associated with corresponding ones of the plurality of wheels, and a simulated brake pedal is operatively associated with the plurality of brakes. The simulated brake pedal is hydraulically isolated from the plurality of brakes. A non-hydraulic braking feedback controller is operatively connected to the plurality of brakes and the simulated brake pedal. The non-hydraulic braking feedback controller selectively provides at least one of a tactile, an audible, and a visual feedback to a driver based on an activation of the simulated brake pedal.

A simulation device for an electrically controlled braking apparatus of a vehicle with an electric motor having a motorized axis slant in relation to the translation axis of the strut of the pedal group, a contrast body connected to the strut, a main abutment wall and an elastic contrast element, disposed between the main abutment wall and the contrast body. The method of applying the contrast action to the pedal provides for activating, when the flattening action of the pedal by the user is terminated, the motor to achieve an inactive configuration in which the useful distance of maximum compression of the elastic contrast element is minimal.

A brake pedal emulator extends and connects between a support structure and a brake pedal pivotally engaged to the support structure at an axis. The brake pedal emulator includes a rotational damping device operatively connected to the brake pedal for driven rotation as the brake pedal moves about the axis.

A vehicle braking system includes a brake pedal, master cylinder, a braking circuit with a wheel cylinder, and a brake pressure generator. A pedal feel simulator is coupled to the master cylinder output side through a switchable valve, the pedal feel simulator providing a reaction force. An isolation valve closes to isolate the braking circuit from the master cylinder and the simulator circuit. A primary pressure sensor generates a braking request signal responsive to the brake pedal. A controller activates the brake pressure generator to apply a braking force to the wheel cylinder based on the braking request signal. The controller identifies an abnormal value from the primary pressure sensor and couples the pedal feel simulator with a secondary pressure sensor within the braking circuit to determine whether the abnormal value indicates a primary pressure sensor malfunction or a malfunction of the pedal feel simulator or the switchable simulator valve.

A brake unit that allows the vehicle to evacuate safely in the event of brake failure while maintaining a braking performance. The brake unit is mounted on a vehicle together with a motor drive unit 2 to control brake force in accordance with a stroke of a brake pedal and a pedal force. Each brake system comprises: a stroke sensor; a pedal force sensor; a brake mechanism applying brake force to a driveshaft; a controller controlling the brake mechanism based on the stroke and the pedal force; and a powersource supplying electricity to the brake mechanism and the controller. The first controller 13 and the second controller support each other to control brake force.

A method for adjusting brake pressures on pneumatically operated wheel brakes of a motor vehicle includes setting, in a normal braking mode, a brake pressure depending on a driver brake request determined by the driver of the motor vehicle and a control unit, during reception of an external brake request which is independent of the driver brake request, in a pressure control mode, sets a resulting brake pressure at the respective wheel brakes taking into account the external brake request and the driver brake request. The method further includes terminating, after revocation of the external brake request, the pressure control mode depending on a comparison of a value representing the driver brake request and entered into the control unit with a predefined threshold value.

A vehicular collision avoidance control device includes: a collision avoidance control unit that receives a vehicle deceleration rate that is an actual deceleration rate of a traveling vehicle and obtains a first desired deceleration rate for avoiding collision with an obstacle based on the received vehicle deceleration rate, a relative distance to the obstacle, and a target relative distance; and a brake control unit that obtains a desired deceleration rate for controlling a brake device by performing first control based on the received vehicle deceleration rate and the first desired deceleration rate and performing second control based on the first desired deceleration rate and stops the first control upon detection of a brake operation performed by a driver.

This electric braking device uses drive torque of an electric motor to push a friction member against a rotating member secured to a vehicle wheel and produce braking torque in the vehicle wheel. This device comprises a body power source for electric motor power supply secured to a body of the vehicle, and a vehicle wheel power source for electric motor power supply secured to the vehicle wheel. The body power source supplies power to the vehicle wheel power source via a first electric path, and the vehicle wheel power source supplies power to the electric motor via a second electric path. When braking torque is produced in the vehicle wheel, the electric motor is normally driven using the vehicle wheel power source. An electric braking device is thereby provided in which a power line electrically connecting the body side and the vehicle wheel side bends readily.

A displacement sensor includes a resistive element and a wiper element. The wiper element is separated from the resistive element in a parked mode the wiper element is in sliding electrical contact with the resistive element in a sensing mode. A user input interface may be coupled to at least one of the resistive element and the wiper element, wherein whether the displacement sensor is in the parked mode or the sensing mode is dependent on actuation of the user input interface.

Provided is an electric booster which can be downsized by enhancing space efficiency while reducing the effect of a magnetic field from outside on a magnetic sensor by means of a magnetic shield. The stroke amount of an input plunger 29 connected to a brake pedal 6 is detected by a stroke detection sensor. The operation of an electric motor is controlled by controller on the basis of the stroke amount of the input plunger to thrust a primary piston through a ball screw mechanism, and brake fluid pressure is thus generated by a master cylinder 4. The stroke detection device uses a Hall IC to detect magnetic flux densities from first and second magnet members mounted on the input plunger to obtain the stroke of the input plunger. The first and second magnet members and the Hall IC are disposed inside a linear-motion member formed of a cylindrical magnetic body of the ball screw mechanism to be magnetically shielded.
