Abstract: A control system for an automotive vehicle having a vehicle body includes a sensor cluster having a housing oriented within the vehicle body. A roll rate sensor is positioned within the housing and generates a roll rate sensor signal corresponding to a roll angular motion of the sensor housing. A controller receives the roll rate sensor signal and generates a reference roll angle. The controller also compares the reference roll angle to the roll rate sensor signal and generates a roll rate sensor fault signal in response a fault determined in said roll rate sensor.

Abstract: By a method for detecting an output-stuck fault of a car body acceleration sensor, an absolute value of a relative difference between the logical car body acceleration operated on the basis of a wheel speed and the physical car body acceleration output from a car body acceleration sensor is obtained, and the obtained absolute value of the relative difference is compared with a first rated value. When the absolute value of the relative difference exceeds the first rated value, a fail counter is made to start to count up at that point of time. When a counted value of the fail counter exceeds one second during the absolute value of the relative difference is exceeding the first rated value, the difference of the maximum value and the minimum value of the physical car body acceleration during the period is compared with a second rated value. When the difference is less than the second rated value, it is judged that the car body acceleration sensor is in its output-stuck fault state in which the output of the sensor does not change to be left to be fixed.

Abstract: The present invention describes a method for detecting a tyre pressure drop in motor vehicles including the following steps: c) producing at least two differently determined reference values Refi which are produced from at least two wheel speed data of the group left front wheel VL, right front wheel VR, left rear wheel HL, and right rear wheel HR (11), and b) detecting a preliminary pressure drop by checking whether at least one reference value Refi includes a predetermined minimum difference from a nominal value Si for this reference value, and a final detection of a pressure drop is considered to prevail in dependence on one or more methods for checking the plausibility. The present invention further describes a method for controlling the brake force and/or the driving dynamics and for implementing the entire method.

Abstract: A method of protecting a control unit of a motor vehicle from manipulation. The control unit is used for the control and/or regulation of the functions of a motor vehicle as a function of at least one operating variable of the motor vehicle. The method is used to protect at least one of the operating variables from manipulation. To prevent a manipulation of the operating variables, the at least one of the operating variables is subjected to a plausibility test using at least one other operating variable of the motor vehicle during operation of the motor vehicle. In particular, a speed signal is subjected to the plausibility test using a rotational speed signal of an internal combustion engine of the motor vehicle and an instantaneous gear ratio of a transmission of the motor vehicle.

Abstract: A circuit arrangement for a safety-critical control system, such as ABS, TCS, ASMS, brake-by-wire, etc., has a dual-circuit or multiple-circuit design, and each circuit includes a complete microprocessor system that processes the input data redundantly and delivers an error identification signal (FAIL) when an error or a discrepancy between the redundantly produced data processing results occurs. Upon error detection, there is a transition to an emergency operation mode where either a circuit is disconnected or the actuator activation of both circuits is assumed by the intact microprocessor system. Each of the two systems is equipped with peripherals of its own, comprised of signal detection, actuator activation, and energy supply.

Abstract: A method and system for determining the operating integrity of a dual sensor system takes in signals from each of the sensors in the dual sensor system. The signals are preferably generally on the same cycle, and the control evaluates whether a single sensor has sent two consecutive cycle signals to the control without a corresponding cycle from the other of the sensors. If so, an indication is made that the other of the sensors may be failing, or is intermittent. Preferably the sensors are associated with wheel speed indicators and the control is an ABS control.

Abstract: A brake by wire system provides the capability of both travel and force sensors on a brake apply input member such as a brake pedal and also provides redundancy in sensors by providing the signal from a sensor responsive to travel or position of the brake pedal to a first controller and the signal from a sensor responsive to force applied to the brake pedal to a second controller. The first and second controllers are connected by a bi-directional communication link whereby each controller may communicate its received one of the sensor signals to the other controller. In at least one of the controllers, linearized versions of the signals are combined for the generation of first and second brake apply command signals for communication to brake apply units. If either controller does not receive one of the sensor signals from the other, it nevertheless generates its brake apply command signal on the basis of the sensor signal provided directly to it from the sensor. In a preferred embodiment of the system, a controller combines the linearized signals by choosing the largest in magnitude.

Abstract: A method for the detection of faulty installation of vehicular motion sensing devices compares the output signals of the sensing devices, which represent angular yawing speed values. Large deviations between these values are interpreted as installation errors, and a control unit causes the dynamic regulation of vehicle movement to be disabled. The particular type of installation error can also be determined by the inventive method, and presented on a display.
