A hydraulic braking system includes: a stroke simulator; a pump configured to suck and discharge working fluid; a hydraulic brake including a brake cylinder connected to the pump; a suction mechanism including a reservoir, a suction portion of the pump, and a suction passage connecting between the reservoir and the suction portion of the pump; a first simulator passage connecting between the stroke simulator and the suction mechanism at a first connecting portion of the suction mechanism; a second simulator passage connecting between the stroke simulator and the suction mechanism in parallel with the first simulator passage at a second connecting portion of the suction mechanism, the second connecting portion being farther from the suction portion of the pump than the first connecting portion; and a flow restricting device provided on the second simulator passage.

Provided is a brake control apparatus mounted in a vehicle with a plurality of wheels, the brake control apparatus including: a actuator configured to apply a braking torque to the plurality of wheels; and a controller configured to control the actuator to apply a first braking torque to a first wheel of the plurality of wheels, based on a spin of the first wheel being greater than or equal to a target spin, and to control the actuator to apply a second braking torque to the plurality of wheels based on a displacement of a brake pedal of the vehicle while applying the first braking torque to the first wheel, wherein the controller stepwise or linearly increases a braking torque applied to a second wheel of the plurality of wheels up to the second braking torque.

In an electric automobile traveling by driving a rear wheel with an electric motor mounted on a vehicle body rear part, a load distributed to the rear wheel is larger than a load distributed to a front wheel by an amount corresponding to a weight of the electric motor. Therefore, it is desirable that a braking force distribution amount to the rear wheel be larger than that to the front wheel. Without providing a proportional pressure reducing valve changing a ratio of braking force distributed between the front and rear wheels, it is possible, by supplying a same brake fluid pressure from a master cylinder to front and rear wheel brake calipers and carrying out regenerative braking in the rear wheel, to make the braking force distribution amount to the rear wheel larger than that to the front wheel.

A rotation angle detection device includes a lever, a cylindrical part, a magnet, and a magnetic sensing element. The lever includes a base and a shaft projecting in the direction of the rotation axis of the base and integrated with the base. The cylindrical part has a first end close to or in contact with the base, and a second end opposite to the first end and farther from the base than the first end. The shaft is inserted in the cylindrical part and is rotatably supported by the cylindrical part. The magnet is attached to the end of the shaft. The magnetic sensing element faces the magnet with a predetermined gap therebetween.

A pedal operating unit having a brake pedal, which is mounted to be pivotable about a first pivot, and a restoring mechanism, wherein the restoring mechanism is designed to apply a restoring force to the brake pedal in the direction of its rest position when the brake pedal is deflected out of the rest position thereof. The restoring mechanism has at least one first restoring device and one second restoring device. An increase in the restoring force is effected, in particular exclusively, by the first restoring device over a first angular range of a pivoting movement of the brake pedal about the first pivot, and an increase in the restoring force is effected, in particular exclusively, by the second restoring device over a second angular range of a pivoting movement of the brake pedal about the first pivot.

A method, for a trailer brake control device of a vehicle trailer with an electric drive, includes receiving at least one acceleration request signal with a requested positive acceleration or a requested negative acceleration and further receiving a status signal with at least one status variable of the electric drive of the vehicle trailer. The method also includes generating, with a controller of the trailer brake control device, at least one brake actuation signal for at least one friction brake of the vehicle trailer and a torque request signal for the electric drive, each based on the at least one acceleration request signal and the status signal. Furthermore, the method includes outputting the brake actuation signal and the torque request signal via at least one output and/or at least one interface of the trailer brake control device.

An angle detection apparatus includes a magnetic detection element, a magnetic field generator, and a first magnetic shield. The magnetic field generator is magnetized along a first direction and generates a magnetic field to be applied to the magnetic detection element. The first magnetic shield surrounds the magnetic detection element along a plane orthogonal to the first direction. The magnetic field generator and the magnetic detection element are rotatable relative to each other around a rotation axis along the first direction.

Systems and methods are provided for controlling one or more brakes of the vehicle. The system may include a processor and a memory in communication with the processor with a brake control module. The brake control module includes instructions that, when executed by the processor, cause the processor to control the one or more brakes of the vehicle when the vehicle is in a first mode using a brake-by-wire system. When the vehicle is in a second mode, control the brake-by-wire system such that the one or more brakes of the vehicle are controlled using a mechanical braking system and the brake-by-wire system.

There is provided a driving assistance device that executes deceleration assistance of a host vehicle when a relative situation between a deceleration object in front of the host vehicle and the host vehicle satisfies a preset deceleration assistance precondition and a driver of the host vehicle does not operate an accelerator and a brake, the driving assistance device including a first deceleration assistance execution unit configured to execute a first deceleration assistance when the deceleration assistance precondition is satisfied in a state in which the driver of the host vehicle does not operate the accelerator and the brake, and a second deceleration assistance execution unit configured to execute a second deceleration assistance when the driver releases the accelerator or the brake in a state in which the deceleration assistance precondition is satisfied.
