An automatic stability control system is provided which senses the lateral acceleration of a vehicle by way of strain gauge sensors, or the like, to provide lateral acceleration signals to an amplifier. Since strain gauge sensors which operate on the piezoelectric effect provide very weak signals, special amplifier circuits must be employed. The amplified signals control a brake assembly on the vehicle to simultaneously, continuously and gradually apply the right and left brakes with a force proportional to the lateral acceleration signals in order to eliminate swerving or swaying of the vehicle. The amplifier is mounted in the vehicle and includes a sensitivity adjustment for setting a threshold point corresponding to a minimum lateral acceleration force to which the system will respond. Sensor configurations are also used which have strain gauges to sense the regular brake fluid pressure of the vehicle in combination with the lateral force sensing sensors. Additional sensitivity adjustments are provided for the amplifiers of these configurations. The control system is primarily adapted for use in a trailing or towed vehicle in combination with a leading or towing vehicle although it is equally effective when used in a single vehicle.
