The utility model is to solve the aforementioned problems in the prior the technical scheme that is adopted to provide a kind of zero-speed electric braking torque control apparatus that is used for regenerative feedback type electric brake tram, the described this zero-speed electric braking torque control apparatus of regenerative feedback type electric brake tram that is used for is by first selector, the signals reverse device, second selector, multiplier, third selector and the 4th finder constitute, wherein, the mouth of described first selector is connected with the input end of described signals reverse device and described second selector, the mouth of described signals reverse device is connected with the input end of described second selector, the mouth of described second selector is connected with the input end of described third selector and described multiplier, another input end of described multiplier is sent into multiplication coefficient 0～5%, the mouth of described multiplier is connected with the input end of described third selector, the mouth of described third selector is connected with the input end of described the 4th finder, and another input end of described the 4th finder inserts zero lock torque signal value.
Further, described first selector, second selector, third selector and the 4th finder are respectively the analog signal selection switches.
Further, the signal input end of described first selector is sent into the level signal that a road is slope/level land state
Further, the signal input end of described second selector is sent into the level signal of a reversing/ahead running state.
Further, the signal input end of described third selector is sent into one does not have/has the level signal of forbidding level land zero-speed electric braking.
Further, the signal input end of described the 4th finder is sent into a level signal of not having/have the electric braking order.
Further, described signals reverse device is the analog signal polarity reverser.
Further, an input end of described first selector makes signal pickup assembly be connected with foot-operated electric braking master, another input end is sent into level land minimum electric braking moment signal value, level land minimum electric braking moment value greater than car speed less than 1～3% datum velocity after vehicle be in moment of inertia on the level land.
Working process of the present utility model is: level signal from slope/level land state to the signal input end of described first selector that send into, send into the level signal of reversing/ahead running state to the signal input end of described second selector, send into the level signal of whether forbidding level land zero-speed electric braking to the signal input end of described third selector, signal input end to described the 4th finder sends into/level signal of no electric braking order, according to the combination of above-mentioned four kinds of different condition of service, select the signal value of the zero-speed electric braking moment of control automatically in the mouth output of described the 4th finder.
Principle of work of the present utility model is: electric car pedal brake main the make signal value pacifically signal value of minimum lock torque of the incoming signal of first selector for gathering in real time, described two input signal values are absolute value signal.The mouth of described first selector is connected with the input end of described signals reverse device and described second selector, the mouth of described signals reverse device is connected with the input end of described second selector, the mouth of described second selector is connected with described multiplier input with described third selector, another input end of described multiplier is sent into multiplication coefficient 0～5%, the mouth of described multiplier is connected with the input end of described third selector, the mouth of described third selector is connected with the input end of described the 4th finder, and another input end of described the 4th finder inserts zero lock torque signal value.Described first selector, second selector, the signal input end of third selector and the 4th finder respectively with level land/slope, reversing/ahead running, do not have/have and forbid level land zero-speed electric braking and nothing/have the level signal of electric braking order to be connected, during application, providing the minimum electric braking moment in level land, on the basis of multiplication coefficient value and zero lock torque signal value, when vehicle real-world operation speed is higher than 1～3% datum velocity or real-world operation speed less than 1～3% datum velocity but the road of vehicle operating when being the slope, the signal input end of described first selector is a low level, first selector is output as the signal value of the main order of pedal brake, and after vehicle real-world operation speed is lower than 1～3% datum velocity, when if the road of vehicle operating is the level land, described first selector signal input end is a high level, then first selector is output as level land minimum electric braking moment signal value, two incoming signals of described second selector are respectively the output signal and the reverse signal behind the signals reverse device of first selector, when the electric car astern operation, described second selector signal input end is a low level, the lock torque signal value of second selector output is identical with the output valve numerical value of described first selector but polarity is opposite, when electric car ahead running moves, described second selector signal input end is a high level, then the lock torque signal value of second selector output is identical with the output of described first selector, when nothing is forbidden level land zero-speed electric braking signal, described third selector signal input end is a low level, and the lock torque signal value of third selector output is identical with the output of described second selector.When forbidding level land zero-speed electric braking signal, the signal input end of described third selector is a high level, then the lock torque signal value of third selector output is that the output signal value of second selector multiply by coefficient 0～5%, and 0～5% selection can be according to preventing that the static requirement of sliding of vehicle from selecting.When electric car does not have the electric braking order, the signal input end of described the 4th finder is a low level, the lock torque signal value of the 4th finder output is zero, when electric car has the electric braking order, the signal input end of described the 4th finder is a high level, then the lock torque signal value of the 4th finder output is the output signal value of third selector, therefore according to described first selector, second selector, third selector and the 4th finder be the signal level of signal input end (different running statees) separately, just can select to control the zero-speed electric braking moment of band regenerative feedback type electric brake tram voluntarily, add different electric braking moment signal values according to different condition of service, can optimize the effect of vehicle electrical stopping-down.
Analog signal selection switch described in the utility model, analog signal polarity reverser, multiplier and foot-operated electric braking master make that signal pickup assembly is the electrician trade known technology, do not repeat them here
