Abstract
Method for monitoring an operating condition of a vehicle including determining a longitudinal, a lateral, and/or a vertical acceleration, as well as a wheel rotation speed. Determining from the wheel rotation speed and the longitudinal, the lateral, and/or the vertical acceleration a tire condition, a wheel condition, and/or a suspension condition. Device including an accelerometer at a wheel of a vehicle, a wheel rotation speed sensor, and a microprocessor for determining an operating condition. The accelerometer determining a longitudinal, a lateral, and/or a vertical acceleration. The wheel rotation speed sensor determining a rotation speed of the wheel. The microprocessor electrically coupled to the accelerometer and the wheel rotation speed sensor. System for monitoring an operating condition of a vehicle including an accelerometer for each wheel of the vehicle at an axle-end. Each accelerometer determining a longitudinal, a lateral, and/or a vertical acceleration. Wheel rotation speed sensor for each wheel of the vehicle arranged at an axle-end and determining a rotation speed for each wheel. Microprocessor determining the operating condition including a tire condition, a wheel condition, and/or a suspension condition. The microprocessor electrically coupled to each accelerometer and each wheel rotation speed sensor.
