Abstract:
1. A method of assessing whether a vehicle equipped with a plurality of wheel brakes is about to overturn, the vehicle being equipped with a single-channel brake pressure modulator arranged to control actuation of the vehicle brakes, comprising the acts of: determining a lateral acceleration of the vehicle; determining a rotational wheel speed of the vehicle wheels; when the lateral acceleration exceeds a predetermined threshold, conducting a rotational wheel speed change test, wherein the test includes monitoring the wheel speed behavior of the vehicle wheels on an inside side of the vehicle, said inside side being the side facing away from the lateral acceleration direction; and determining based on monitored wheel speed behavior whether the vehicle is about to overturn, wherein in the overturn determination step, if the vehicle is being braked, the vehicle is determined to be about to overturn when the wheel speed of the inside wheels increases at a greater rate than the wheels on an outside side of the vehicle.
