This paper will explain the C5 Corvette Active Handling (AH) control strategy formulated around the base vehicle characteristics and additional integrated components. The new chassis control strategy uses electrohydraulic brake pressure at all four corners to input braking forces independent of the driver. AH was designed to assist the driver in controlling the vehicle during limit handling situations. The primary inputs to the chassis control strategy are vehicle speed, steering wheel angle, yaw rate about a vertical axis passing through the vehicle's c.g., brake pressure and lateral acceleration. Vehicle ride demonstrations and vehicle modeling were used to show the benefit of Active Handling.

This paper presents the engineering technology for the 1992 Corvette Acceleration Slip Regulation (ASR) system and Antilock Brake System (ABS). After the introduction of Bosch 2S anti-lock brakes in the 1986 Corvette, we experienced an improvement in vehicle stability and steerability during hard braking. The next challenging task was to improve the vehicle's stability during acceleration. The goal was to assist the driver of this high horse power front engine, rear wheel drive sports car on low coefficient surfaces. This goal was accomplished with the functional integration of engine torque management and brake intervention. This required functional integration of three subsystems: engine spark retard, throttle close down and brakes. This is the first application for a throttle close down device which provides driver feed back of slippery road conditions, through the accelerator pedal.
