An on-vehicle control device includes: a control unit that controls an attitude of a vehicle based on a value of a behavior sensor that detects a behavior of the vehicle, and prohibits control based on the behavior sensor when the value of the behavior sensor exceeds a threshold; and a travel environment determination unit that determines a travel environment of the vehicle based on image information captured by a camera, and in which the control unit changes the threshold to a lower value based on the travel environment determined by the travel environment determination unit.

An integrated circuit (IC) chip for providing a safety-critical value includes first and second processing paths. The first processing path includes a first processing element and is coupled to receive a first input signal on a first input pin and to provide a first output signal that provides the safety-critical value on an output pin. The second processing path includes a second processing element and is coupled to receive a second input signal and to provide a second output signal. The first processing path and the second processing path are independent of each other. A smart comparator on the IC chip receives the first output signal and the second output signal and initiates a remedial action responsive to a difference between the first output signal and the second output signal reaching a configurable threshold.

Embodiments relate to systems and methods for sensor self-diagnostics using multiple signal paths. In an embodiment, the sensors are magnetic field sensors, and the systems and/or methods are configured to meet or exceed relevant safety or other industry standards, such as SIL standards. For example, a monolithic integrated circuit sensor system implemented on a single semiconductor ship can include a first sensor device having a first signal path for a first sensor signal on a semiconductor chip; and a second sensor device having a second signal path for a second sensor signal on the semiconductor chip, the second signal path distinct from the first signal path, wherein a comparison of the first signal path signal and the second signal path signal provides a sensor system self-test.

When detecting a maladjusted brake component on a commercial vehicle, wheel end temperature is determined as a function of resistance measured by a wheel speed sensor at a wheel end. The measured temperature is compared to low and high temperature thresholds defined by a thermal model, as well as to one or more other wheel speed sensor temperatures. If the measured temperature is below the low temperature threshold and substantially different than the one or more other wheel speed sensors, the brake is determined to be under-adjusted and brake force at the under-adjusted brake is increased. If the measured temperature is above the high temperature threshold and substantially different than the one or more other wheel speed sensors, then the brake is determined to be over-adjusted, and brake force is reduced or modulated at the over-adjusted brake to prevent overheating.
