Detailed description of the invention
As shown in Figure 1.In the present invention, form step configuration by Das Gaspedal 10 and brake pedal 12, install pedal sensor 11,13 in Das Gaspedal, brake pedal respectively, two pedal sensors can select pedal position sensor.Accelerator and brake control module 15 connects the pedal sensor 11,13 in step configuration by automotive wire bundle 20, accelerator and brake control module 15 is also by CAN 38 connecting engine control unit ECU40.Brake Power assisted control module 21 is by CAN connecting engine control unit ECU40, brake booster device 24 is arranged in automobile brake system, brake power-assisted feedback transducer 25 is arranged on brake booster device 24, the optional torque sensor of brake power-assisted feedback transducer 25, brake power-assisted feedback transducer 25 is by automotive wire bundle connecting engine 33 control unit ECU40.Throttle control module 26 is by CAN bus connecting engine control unit ECU40, throttle gate 30 accesses throttle control module 26 and is controlled by throttle control module 26, throttle gate 30 carries throttle sensor 32, and throttle sensor 32 is by automotive wire bundle direct connecting engine 33 control unit ECU40.
Accelerator and brake control module 15 is by CPU18 and the I/O interface module 16, read only memory ROM 17, the random access memory ram 19 that access CPU18 respectively, and pedal sensor accesses the CPU18 of accelerator and brake control module 15 by I/O interface module 16.
Brake Power assisted control module 21 is made up of the brake booster device driving circuit 23 of controller 22, access controller 22, and brake booster device 24 accesses on the driving circuit 23 in brake Power assisted control module 21.
Throttle control module 26 is made up of the throttle valve drive circuit 28 of controller 27, access controller 27, and throttle gate 30 accesses on the throttle valve drive circuit 28 in throttle control module 26.
As shown in Figure 2.Chaufeur steps on brake pedal 12, pedal sensor 13 on brake pedal exports brake pedal feedback signal, accelerator and brake control module 15 receives the output signal of pedal sensor 13, brake pedal signal value output and signal duration are judged, when brake pedal 12 signal value output and signal duration meeting accelerator and brake control module 15 setting value, accelerator and brake control module 15 sends control unit of engine ECU40 to brake pedal 12 signal value output now, control unit of engine ECU40 to enter after comparison this signal transmission to brake Power assisted control module 21, the signal that brake Power assisted control 21 provides according to control unit of engine ECU40 applies corresponding power-assisted to automobile brake system, automobile enters the brake mode that chaufeur is wanted.Now chaufeur is without the need to applying any power to brake, the pin of pedal of touching on the brake obtains short time liberation, until chaufeur is wanted to remove brake power-assisted, brake is allowed to recover normal condition, need only light accelerator pedal 10, whether the signal that the pedal sensor 11 in Das Gaspedal 10 exports, by accelerator and brake control module 15, judges signal in the scope of setting value removing Power assisted control module 21 of braking in accelerator and brake control module 15, if within the scope of it, accelerator and brake power-assisted automatically terminates.
When brake pedal 12 signal value output and signal output time can not meet brake Power assisted control module 21 setting value, accelerator and brake control module 15 does not export any signal to control unit of engine ECU40, and braking automobile is still in normal condition.
As shown in Figure 3.Chaufeur steps on Das Gaspedal 10, pedal sensor 11 in Das Gaspedal exports Das Gaspedal 10 feedback signal, accelerator and brake control module 15 receives accelerator pedal sensor 11 output signal, Das Gaspedal 10 signal value output and signal duration are judged, when Das Gaspedal 10 signal value output and signal output time meet accelerator and brake control module 15 setting value, accelerator and brake control module 15 sends control unit of engine ECU40 to Das Gaspedal 10 signal value output now, control unit of engine ECU40 to enter after comparison this signal transmission to throttle control module 26, the valve block 31 of the signal throttle valve 30 that throttle control module 26 provides according to control unit of engine ECU40 is stable to be remained in open range corresponding to this signal, air input of engine by air is now made to remain in the scope of corresponding valve block 31 aperture, under automobile enters the automatic uniform speed pattern that chaufeur wants.Now chaufeur is without the need to applying any power to Das Gaspedal 10, the pin of accelerator pedal 10 obtains short time liberation, until chaufeur is wanted to convert moving velocity, chaufeur is wanted to remove throttle force aid system, Das Gaspedal 10 is allowed to recover normal condition, gently need only be touched on the brake pedal 12, the signal that pedal sensor 13 on brake pedal 12 exports is by accelerator and brake control module 15, accelerator and brake control module 15 judges that signal is in the scope of the setting value removing brake power assist controller 21, if within the scope of it, throttle force aid system automatically terminates.
When Das Gaspedal 10 signal value output and signal output time can not meet accelerator and brake control module 15 setting value, brake Power assisted control module 21 does not export any signal to control unit of engine ECU40, and braking automobile is still in normal condition.
