A brake system for a motor vehicle comprises a first brake set and second brake set. A first hydraulic brake circuit is connected to the first brake set and a second hydraulic brake circuit is connected to the second brake set. Further, a first control module is coupled to the first hydraulic brake circuit and the second hydraulic brake circuit. The first control module is configured to control fluid pressure within both the first hydraulic brake circuit and the second hydraulic brake circuit. A second control module is also coupled to the first hydraulic brake circuit and the second hydraulic brake circuit. The second control module is configured to control fluid pressure within both the first hydraulic brake circuit and the second hydraulic brake circuit independent of the first control module. The first control module is disposed in series with the second control module in the first and the second hydraulic brake circuits. Additionally, a virtual driver sends a deceleration request to the first control module and the second control module. The first control module and the second control module determine a desired pressure based upon the deceleration request. The first brake control module controls fluid pressure within both the first and the second hydraulic brake circuits to perform the deceleration request. The second control module monitors pressure downstream from the first control module and compares the monitored pressure to the desired pressure.

Fault-tolerant redundant by-wire brake system

Disclosed is a method of improving the recognition of a tire pressure loss in a tire pressure monitoring system in which at least one reference value (A) is formed on the basis of signals representing the rotational speeds of several vehicle wheels. A pressure loss is concluded by comparing a currently determined reference value with at least one reference value if the currently determined reference value exceeds or falls short of a predefined value. A noise analysis of the reference value(s) () is executed and at least one threshold value (T, S) is adjusted () based on the result of the noise analysis ().

Method for improving an indirectly measuring tire pressure monitoring system

The present invention features a system and method for estimating body states of a vehicle. The system includes at least two sensors mounted to the vehicle. The sensors generate measured vehicle state signals corresponding to the dynamics of the vehicle. A signal adjuster transforms the measured vehicle states from a sensor coordinate system to a body coordinate system associated with the vehicle. A filter receives the transformed measured vehicle states from the signal adjuster and processes the measured signals into state estimates of the vehicle, such as, for example, the lateral velocity, yaw rate, roll angle, and roll rate of the vehicle.

Body state estimation of a vehicle

The present invention is directed to a system for determining lift-off or wheel departure of one or more wheels associated with a vehicle from a road. The system includes a sensor that measures the wheel speed of at least one wheel, and a controller that calculates the resonance frequency of the at least one wheel, calculates variations in the resonance frequency, compares the variations with a threshold, and indicates lift-off of the wheel from the road if the variations exceed a threshold.

System to measure wheel liftoff

A system that detects a lateral acceleration and roll rate of the vehicle and estimates a mass distribution parameter. The system then generates a tuned mass distribution parameter that is based on the the lateral acceleration, the roll rate, and the mass distribution parameter and introduces the tuned mass distribution parameter to a rollover stability control system.

Reduced order parameter identification for vehicle rollover control system

A system and method protects against rollover in a vehicle by employing an array of linear acceleration sensors. A control module includes, among other things, a model of the vehicle dynamics and a model of the array of sensors. A state vector is estimated based on the detected accelerations, the model of the vehicle dynamics and the model of the sensors. A control signal is generated based on the state vector, and the roll moment of the vehicle is reduced based on the control signal.

Active rollover protection

A stability control system and method is provided for decreasing the propensity for rollover and preventing a rapid body roll movement after active management by the stability control system. The control system and method recognizes a propensity for vehicle instability, modifies the tire force vector of the vehicle's wheel to increase stability, and returns the tire force vector at a limited rate to prevent an impulse force on the wheel. The tire force vector may be held for a period of time after the propensity for vehicle instability is no longer recognized. A logic block is provided for determining the propensity for the impulse force on the wheel, which results in control of the proportional control signal or other signal to regulate the control input that is sent to the braking or steering control system.

Method to mitigate vehicle roll oscillations by limiting the rate of recovery of the lateral component of the tire force vector

The present invention involves a system and method of regulating manual control for a driver of a vehicle during a sliding condition of the vehicle having an electronic stability program using a stability control system. The method includes recognizing the vehicle in a sliding condition and determining whether the vehicle is manually controllable in the sliding condition. The method further includes adjusting the electronic stability program, if the vehicle is determined to be manually controllable, and activating the stability control system to control the vehicle when the vehicle is not manually controllable. The method further includes applying a compensated brake pressure on the vehicle based on the activation of the stability control system.
