A rotation angle detection device for a vehicle brake includes: a housing accommodating a magnetic detection unit; a rotation member supported to be rotatable relative to the housing; and a magnet held by the rotation member and rotating integrally with the rotation member, in which the magnetic detection unit includes a stroke detection unit and a switch detection unit, the stroke detection unit detects a rotation angle by which the rotation member has rotated from a reference position based on a magnetic force of the magnet, the switch detection unit detects that the rotation member has rotated from the reference position by a predetermined angle or more, and at least a portion of the stroke detection unit is disposed at a position where the portion overlaps with the magnet in an axial direction of a rotational axis of the rotation member.

In an information providing method for a vehicle, an engine is stopped automatically when a predetermined permission condition is satisfied in a state in which the vehicle is stopped by a brake operation executed by a driver. The permission condition is a brake operation amount of a brake having reached a predetermined brake operation amount. The driver is notified of support information prompting the driver to increase the brake operation amount when the permission condition is not satisfied after a predetermined time has elapsed since the vehicle was stopped. A braking force capable of maintaining a vehicle stop state is generated by a vehicle stop keeping control. The driver is notified of the support information when the brake operation amount decreases before the predetermined time has elapsed in a state in which the vehicle has been stopped by the brake operation and the vehicle stop keeping control is executed.

Disclosed herein is an installation structure for a pedal stroke sensor, including: a piston configured to move forward and backward by an operation of a pedal; a mounting member disposed on the piston; a first shaft coupled with the mounting member; a second shaft including a second gear engaged with a first gear of the first shaft; and a measuring portion disposed on the second shaft.

A brake control apparatus according to an embodiment of the present disclosure includes a braking device configured to generate a braking pressure based on a hydraulic pressure to provide a main braking force to a vehicle; and a controller configured to control at least one control module selected based on the speed of the vehicle among a plurality of control modules including an engine control module (EMS) of the vehicle, a motor control module and a parking brake control module to provide an auxiliary braking force to the vehicle when the braking device is in an abnormal state.

A brake system control unit for a vehicle having a hydraulic vehicle brake and electromechanical brake device comprises a microcontroller, a system ASIC and a brake motor ASIC, wherein the microcontroller is connected to the system ASIC and the brake motor ASIC via communication interfaces. In the brake motor ASIC, an interrogation signal sequence for interrogating the switched state of an actuation switch of the electromechanical brake device is generated.

A hydraulic pressure generating device includes a base body, a master cylinder provided on the base body and configured to generate a brake hydraulic pressure by a first piston connected to a brake operating element, a housing attached to the base body, a control board contained in the housing, a stroke sensor configured to detect an amount of movement of the first piston; and a detection object member which is detected by the stroke sensor. The housing has a facing wall portion provided so as to face the base body. The stroke sensor is provided inside the housing on the opposite side of the facing wall portion to the base body, and is electrically connected to the control board.

Provided are an electronic brake system and a method of controlling the same. The electronic brake system includes a pedal input unit configured to receive a pedal force according to a driver's braking intention, an estimating unit configured to estimate a temperature and a friction coefficient of a brake disk pad, and a control unit configured to correct a braking target pressure according to the driver's braking intention on the basis of the estimated temperature and friction coefficient of the brake disk pad.

A rear automatic braking system is automatically overridden and released if the accelerator pedal is depressed with the rate of change which is greater than empirically determined threshold beyond a predetermined percentage of its travel for at least a predetermined length of time and if the vehicle's brake pedal is not depressed.

A brake boost assist system for use with a master cylinder of a motor vehicle braking system, includes an inductive sensing system. The inductive sensing system has sensing devices carried on an input member and an output member, where the input and output members are coupled to respective ones of an input rod and an output rod of the brake boost assist system. Movement of the input and output members relative to one another, and relative to a fixed element of the inductive sensing system positioned within the brake boost assist system, enables an accurate estimation of the distance of a pedal gap which separates faces of the input and output rods. The accurate estimation of the pedal gap distance enables a more accurate determination to be made of the braking force required for any given pedal stroke input by an operator of the vehicle during a braking action.
