A vehicle braking device includes: a brake fluid pressure generation device arranged in a storage chamber separated from a vehicle cabin; and a brake operation part mechanically connected to the brake fluid pressure generation device, the brake operation part being not provided in the vehicle cabin. The brake fluid pressure generation device includes a cylinder and pistons configured to slide inside the cylinder. The brake fluid pressure generation device is configured to generate brake fluid pressure in accordance with strokes of the pistons. The brake fluid pressure generation device is arranged such that a sliding direction of the pistons is along a direction different from the vehicle front-rear direction in a plan view.

Vehicle braking device

An on-board brake system mounted in an autonomous vehicle comprises a brake unit, a first brake actuator and a second brake actuator for driving the brake unit, and a main ECU for controlling drive of the first and second brake actuators; the second brake actuator is an accumulating actuator; and when an emergency stop switch is depressed, the main ECU operates only the second brake actuator or operates the second brake actuator with precedence over the first brake actuator.

On-board brake system

A vehicle includes a vehicle cabin, a storage chamber, and a partition wall separating the storage chamber from the vehicle cabin. The storage chamber is arranged on at least one side of the vehicle cabin in the vehicle front-rear direction. The partition wall has an opening and the storage chamber communicates with the vehicle cabin via the opening. A cover configured to open and close the opening is provided over the opening. A brake fluid pressure generation device is stored in the storage chamber. The brake fluid pressure generation device includes a reservoir tank in which hydraulic fluid is accumulated and is arranged at a position facing the opening.

Vehicle

A braking system is provided. The braking system includes a plurality of brake fluid pressure generation devices provided in a front-side storage camber of a vehicle in which automated driving is enabled. The brake fluid pressure generation devices are provided on the same fluid pressure transmission route and include a non-electrically actuated brake pedal unit. The braking system includes an emergency stop button provided in a vehicle cabin, and an emergency brake circuit that generates braking force with use of the brake pedal unit in a non-energized state or in a case of transition to the non-energized state after the emergency stop button is operated.

Braking system

An electric vehicle includes: a motor; a braking device for wheel braking, the braking device including a brake fluid pressure generation device; an air-conditioning device; and a battery as a power source for the motor. The vehicle is not provided with a driver seat that allows a user to operate a steering wheel, an accelerator pedal, and a brake pedal in a state where the user sits on the driver seat, and the vehicle is configured to perform automated driving. A first storage chamber and a second storage chamber are provided in a first end portion and a second end portion of the vehicle in the vehicle front-rear direction, respectively, such that the first storage chamber and the second storage chamber partially overlap a vehicle cabin in the vehicle front-rear direction. A third storage chamber is provided under a floor of the vehicle cabin.

Electric vehicle

An electrically powered vehicle having a generally rectangular appearance includes a rear seat disposed in a rear of a cabin of the vehicle; a main battery disposed under a floor in a center of the cabin; a power unit compartment disposed below the rear seat; a driving motor disposed in the power unit compartment; a PCU disposed above the driving motor; an ECU disposed above the PCU; and an auxiliary battery disposed in the power unit compartment.

Electrically powered vehicle

Provided is a brake bleeding device for bleeding air accumulated in brake fluid inside a braking device provided in a vehicle. The brake bleeding device includes: a master cylinder constituting a part of the braking device and provided inside a front-side storage chamber, the master cylinder being configured to generate brake hydraulic pressure in accordance with a stroke of an input piston; a brake pedal unit provided inside the front-side storage chamber and configured to give pressing force in a stroke direction to the input piston when a link mechanism connected to the input piston via a rod is operated; and an operating lever attached to the link mechanism in a state where the link mechanism is operable by the operating lever. The operating lever extends downward to a position where the operating lever is accessible from outside the front-side storage chamber.

Brake bleeding device

A disc brake device () includes: a disc rotor () rotatable around its rotation axis; a pair of brake pads () provided opposite to each other on both sides of the disc rotor in an axial direction along the rotation axis; and a pressing mechanism () able to press the brake pads against the disc rotor from both sides of the disc rotor with pistons () provided opposite to each other on both sides of the disc rotor in the axial direction. Each brake pad has a friction material () facing a corresponding friction face () of the disc rotor. The number of slits () provided in the friction material of one of the brake pads and not passing through any pressing portions pressed by the pistons is different from the number of slits provided in the friction material of the other one of the pair of brake pads and not passing through any pressing portions.

Disk brake device and pair of brake pads

According to an example, a disk brake is disclosed in which a caliper is supported by a mounting bracket via a slide pin, the mounting bracket being attached to a non-rotational portion of a vehicle, the disk brake comprising an electromagnet provided in connection with the slide pin, the electromagnet attracting the slide pin in an axial direction of the slide pin such that brake pads move away from a disk rotor. According to another example, a disk brake in which a caliper is supported by a mounting bracket via a slide pin, the mounting bracket being attached to a non-rotational portion of a vehicle, the disk brake comprising a magnetic material body of a backing plate of a brake pad and an electromagnet provided in a location where the electromagnet is opposed to the magnetic material body in a lateral direction of the vehicle.
