Transmitting element, when accelerating top line for arriving at described Motor Vehicle headstock, sending and accelerating controlled quentity controlled variable; When the described Motor Vehicle tailstock arrives accelerating terminal line, then send deceleration controlled quentity controlled variable;
ECU (Electrical Control Unit), when accelerating top line for arriving at the headstock of described Motor Vehicle, handling long-range throttle according to described acceleration controlled quentity controlled variable and realizing the acceleration of described Motor Vehicle; When the described Motor Vehicle tailstock arrives accelerating terminal line, handle long-range throttle according to described deceleration controlled quentity controlled variable and realize described reducing speed of motor vehicle.
5. system according to claim 4, is characterized in that, described stability requirement specifically comprises:
The change of described motor vehicle speed controls within ± 1km/h; Or described motor car engine rotation speed change controls ± 2% or ± 50r/min, or gets the higher value in described two ranges of speed control.
6. system according to claim 4, is characterized in that, described ECU (Electrical Control Unit) also comprises:
Judging unit, for when the described Motor Vehicle tailstock is by accelerating terminal line, judges whether described motor car engine rotating speed exceedes rated speed, if so, then provides process control and stops prompting, otherwise, then continue described process control procedure.
