This papers describes a vehicle control law with driving load adaptation for application to a stop and go cruise control. Gravitation force due to road slope is a large unknown disturbance in vehicle dynamic model. Throttle switching line is tuned to flat land. It is not proper to slop land. Throttle, brake switching line has been adapted using a driving load estimation method. Driving Load is estimated from engine speed, turbine speed, brake pressure and vehicle acceleration using simplified vehicle dynamic model and a least square method. The performance of the control law is investigated via simulation and experiment test. The simulation and experiment test show that the proposed control law can reduce distance error and speed error.

The fuel pump should supply fuel to the engine during the all driving condition but in case of the high power turbo-GDI engine, it usually consumes lots of fuel at the high speed circuit driving condition. At this case of severe circuit driving condition, the fuel pump suction point is separated with fuel in the fuel tank because of excessive lateral acceleration. If the vehicle is driven wide open throttle driving after excessive lateral accelerations. This results in fuel pressure decrease, engine hesitation and stall due to lack of fuel in the fuel pump reservoir.
