Examples herein include a brake hydraulic pressure control device and a brake hydraulic pressure control method capable of preventing a rear wheel of a saddle-type vehicle from lifting. The brake hydraulic pressure control device of a saddle-type vehicle is configured to execute anti-lock brake control and determine an opening time of one opening of a hydraulic pressure adjusting valve, and control the hydraulic pressure adjusting valve to repeatedly open for the opening time and close a main flow path, causing a brake fluid to flow from a master cylinder to a wheel cylinder. A pressure of the brake fluid in the wheel cylinder is increased after a decrease in the pressure of the brake fluid in the wheel cylinder during the anti-lock brake control. The opening time is determined according to the pressure of the brake fluid in the master cylinder and the input gradient of the brake lever.

A front tire heating and cleaning system for a vehicle includes a brake system configured to selectively apply hydraulic braking pressure against front wheels and rear wheels of the vehicle, and a controller in signal communication with the brake system. The controller is configured to, upon receipt of a request, initiate a controlled front tire heating mode where the brake system is controlled to selectively apply hydraulic braking pressure against the rear wheels and not the front wheels, and rotate the front wheels to increase tire temperature for improved front wheel traction during off-road maneuvers.

A brake assist system for a cyclist on a bicycle by a haptic feedback includes: a first sensor for measuring the angular speed of a first bicycle wheel, suitable for generating a signal representing the first wheel angular speed; a second sensor for measuring the angular speed of a second bicycle wheel, suitable for generating a signal representing the second wheel angular speed; an actuator applicable to a bicycle portion, suitable for producing vibrations; and a control module.

A vehicle brake system having electronic pressure regulation and a related method, in which the system stabilizes a vehicle, supports the actuation of the brake system, and/or enables a fully/partly automated driving operation. The system has a primary actuator system that sets/regulates different brake pressures at the wheel brakes, and an electronically controllable secondary actuator system that secures the vehicle brake system against primary actuator failure. For a primary actuator error, the secondary actuator is controlled so that the secondary system produces a brake pressure that, based on the dynamic axle load displacement, occurring during a braking process, in the direction of a front axle, is greater than the brake pressure that is convertable into a rear axle wheel brake braking power. A device reduces this brake pressure at the rear axle wheel brake to a value at which the vehicle wheel, assigned to this wheel brake, does not lock.

A braking system for a vehicle includes: a front axle wheel brake cylinder; a rear axle wheel brake cylinder; and a control electronics system for controlling a first brake pressure in the front axle wheel brake cylinder and/or a second brake pressure in the rear axle wheel brake cylinder. A limiting value z-critical is defined for the braking system, which specifies a maximum braking action, at which a traction stress on the front axle of the vehicle and a traction stress on the rear axle of the vehicle are equal. The braking system is mechanically configured for a z-critical of at least 0.7 g, and the braking system is controlled by the control electronics system during operation using a z-critical value of at most 0.7 g.

Methods and systems are provided for operating a hybrid vehicle during operating conditions where vehicle braking is requested. In one example, regenerative braking is allocated to vehicle axles responsive to wheel torques of respective vehicle axles in response to an anti-lock braking system being activated. Additionally, friction braking torque is allocated to vehicle axles responsive to the anti-lock braking system being activated.

A braking force control apparatus is provided which has a first system including a first upstream braking actuator and a first downstream braking actuator, a second system including a second upstream braking actuator and a second downstream braking actuator, and a control unit. When the downstream braking actuator is abnormal and the upstream pressure can be supplied to braking force generating devices, but a braking pressure of any one of the wheels cannot be normally controlled, the control unit select the pressure increasing side control mode out of the front wheel control modes as a first prescribed control mode, select the pressure decreasing side control mode out of the rear wheel control modes as a second prescribed control mode, and to control the first and second upstream pressures in the first and second prescribed control modes.
