A method for operating a brake system of an at least double-tracked motor vehicle comprises two breakable wheels, which are arranged at opposite ends of an axle, and a rollover protection system which can cause braking of the wheels in order to prevent a rollover situation. Automatic braking of that wheel of the axle which is loaded more greatly when cornering is brought about by way of the rollover protection system. Subsequently, a smaller steering lock angle or a lower lateral acceleration than in the case of the cornering which took place immediately previously, or a straightahead driving phase which immediately follows the cornering is detected. Thereupon, automatic braking of the two wheels on the axle is brought about.

In the case of a method for operating a brake system of an at least double-tracked motor vehicle (10) which comprises 2 breakable wheels (12.sub.L, 12.sub.R), which are arranged at opposite ends of an axle (14.sub.V), and a rollover protection system, which can cause braking of the wheels (12.sub.L, 12.sub.R) in order to prevent a rollover situation, automatic braking of that wheel of the axle (14.sub.V), which is loaded more greatly when cornering is brought about by way of the rollover protection system. Subsequently, a counter-steering movement is detected by way of a predefined steering angle change being exceeded in a predefined time period in the direction counter to the cornering direction, and, thereupon, a brake force is caused to be built up at the opposite wheel, which is loaded less greatly by way of the rollover protection system.

An electronic brake system according to an embodiment of the present disclosure includes a first pedal travel sensor and a second pedal travel sensor each including two internal sensors and outputting a pedal detection signal according to an operation of a brake pedal; and a first ECU (electronic control unit) may receive a first pedal detection signal from a first internal sensor of the first pedal travel sensor and receive a second pedal detection signal from a second internal sensor of the second pedal travel sensor, and a second ECU may receive a third pedal detection signal from a third internal sensor of the first pedal travel sensor and receive a fourth pedal detection signal from a fourth internal sensor of the second pedal travel sensor.

A method of operating a brake system for a motor vehicle, the brake system has a parking brake device and actuating the parking brake device for generating a parking braking force on a wheel of the motor vehicle is only permitted if a speed value falls below a speed threshold value. As such, the speed value is determined from a measured speed value corresponding at least temporarily to a speed of the motor vehicle. If the measured speed value falls below the speed value, the speed value is made to track the measured speed value with a speed gradient limited to a speed gradient limit value.

A stably braking system and a method using the same control wheels on a single axle of a ground vehicle. Firstly, at least one of a wheel deceleration and an actual slip of each of the wheels is calculated. Hydraulic control commands are generated when a braking operation is performed in response to a braking indication signal and it is detected that the wheel deceleration or the actual slip is higher. The hydraulic control commands are configured to control a hydraulic braking system to adjust the wheel speed. When the ground vehicle drives in a straight line or turns with a first pose physical quantity, the hydraulic control command with a low priority is replaced by the hydraulic control command with a high priority and the hydraulic braking system is controlled to adjust the wheel speeds based on the identical hydraulic control commands.

A hydraulic motor vehicle braking system includes a first sensor device, a first functional unit, a second functional unit and a switching device. The first functional unit comprises at least one first electrical brake pressure generator, by means of which a brake pressure can be generated on respective wheel brakes, and a first control system which is designed to control the at least one first electrical brake pressure generator on the basis of a sensor signal of the sensor device. The second functional unit comprises at least one second electrical brake pressure generator, by means of which a brake pressure can be respectively generated on a subset of the wheel brakes, and a second control system which is designed to control the at least one second electrical brake pressure generator on the basis of the sensor signal in the event of a failure of the first functional unit.

An apparatus for determining a wheel condition on whether wheel locking occurs in each wheel of a vehicle having a main brake apparatus and an auxiliary brake apparatus. The apparatus includes: a WSS (Wheel Speed Sensor) configured to primarily detect whether wheel locking occurs; a TPMS (Tire Pressure Monitoring System) configured to secondarily detect whether wheel locking occurs; and a control unit configured to determine, when the WSS fails, a wheel condition indicative of whether wheel locking occurs in each wheel, by using information detected through the TPMS.

A control device may be configured for responding to failure for ensuring the stability of a vehicle by switching from a two-wheel-drive mode to a four-wheel-drive mode when detecting failure of the brake system in a two-wheel-drive mode.

A vehicle brake control device including a front wheel speed acquisition section, a rear wheel speed acquisition section, a front wheel acceleration calculation section, a rear wheel acceleration calculation section, a front wheel anti-lock brake control section capable of executing an anti-lock brake control for the front wheel, a vehicle acceleration acquisition section, and a bad road determination section configured to determine whether or not a running road surface is a bad road based on the front wheel acceleration or the rear wheel acceleration. The bad road determination section executes a bad road determination by selectively using one of the front wheel acceleration and the rear wheel acceleration at least based on information on whether or not the anti-lock brake control for the front wheel is executed and the vehicle acceleration.

A brake rotor assembly and a method of assembly. The brake rotor assembly includes a brake rotor, a tone ring, and a rivet. The rivet is disposed in a hole in the brake rotor and a hole in the tone ring and fixedly secures the tone ring to the brake rotor.
