Abstract
A vehicle control apparatus and method therefor has a number of controllers (50, 63, 56) interconnected with one another by a data highway (10), the engine controllers being formed for example by a CPU. The engine controllers are each connected to a sensor for sensing a vehicle parameter and the controllers are also connected to a respective actuator (53, 58) for varying the associated vehicle parameter. The apparatus is arranged so that the controllers operate in cooperation with one another so that two or more controllers cooperate to control the same object or purpose. As an example (shown in FIG. 20) an engine controller (50) provides torque data to a transmission controller (63) which in turn provides data to a throttle controller (56), whereby a gear shift is effected by the transmission controller (63) in synchronism with the throttle controller (56) changing the position of a throttle actuator so that a jerk-free gear shift is effected. In another embodiment (shown in FIG. 33) an engine controller (50) cooperates with a throttle controller (56) and a suspension controller (64) whereby data from the engine controller determining whether the vehicle is accelerating or braking…
