Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and it is not intended that the utility model
Limitation.
Below in conjunction with pedal position detection device of the attached drawing description according to the utility model embodiment, pedal position sensor
And vehicle.
Fig. 1 is the structure diagram according to the pedal position detection device of the utility model one embodiment.As shown in Figure 1,
According to the pedal position detection device of the utility model one embodiment, including：Pedal position sensor 110 and controller 120.
Wherein, pedal position sensor 110 includes detecting for detecting the first detection port 111, second of pedal position
Port 112 and third detection port 113, wherein, port 112 and third detection port are detected in the first detection port 111, second
113, which correspond to the first detection signal of output, the second detection signal and third detection signal, has preset ratio relationship.Controller
120 detect port 112 and third detection port 113 with the first detection port 111, second respectively is connected, with according to the first detection
The ratio-dependent first that signal to third detects signal and/or first detection signal to third detection signal detects port 111, the
In two detection ports 112 and third detection port 113 one there are during failure, it is true with the detection signal of other two detection port
Determine pedal position.
With reference to shown in Fig. 1, the first detection port 111, second is detected port 112 and third detection port 113 and is respectively provided with solely
Port 112 and third test side are detected in vertical power supply port (being made of power end and ground terminal), the first detection port 111, second
The power supply port of mouth 113 is powered by controller 120.
In specific example, preset ratio relationship is, for example, 3:2:1, with reference to shown in Fig. 2, pedal position is in and goes back original position
When (unclamping the nature after pedal) and maximum position (end stop final positions), first detection signal is 15% He
72%th, the second detection signal is 10% and 48%, third detection signal is 5% and 24%.
Specifically, pedal position sensor 110 has three road signals, and three road signals are independently-powered and are grounded, such as Fig. 2
It is shown, show three detection characteristics of signals of the output of pedal position sensor 110, first detection signal Sensor1 (U1/
U0)：Second detection signal Sensor2 (U2/U0)：Third detection signal Sensor3 (U3/U0)=3:2:1.
During nature, the first detection signal Sensor1=15% of the output of pedal position sensor 110, the second detection
Signal Sensor2=10%, third detection signal Sensor3=5%, when bend the throttle, sensor signal linearly becomes
Change, during final position, first detection signal Sensor1=72% that pedal position sensor 110 exports, the second detection signal
Sensor2=48%, third detection signal Sensor3=24%, controller 120 carry out the control of torque as input.
Controller 120 can detect signal and/or first detection signal to third according to first detection signal to third and examine
One has event in the detection of ratio-dependent first port 111, the second detection port 112 of survey signal and third detection port 113
During barrier, pedal position is determined with the detection signal of other two detection port, is stepped on specifically, controller 120 can be diagnosed to be
The following failure of Board position sensor：
1st, as the U/U0 ＜ 3% of signal, signal wire shorted to earth or signal wire open circuit；
2nd, as the U/U0 ＞ 95% of signal, signal wire is to power supply short circuit；
3rd, when U1/U0 is not in the range of 15%-90% or when U2/U0 is not in the range of 10%-60% or U3/U0 does not exist
When in the range of 5%-300%, signal overruns；
4th, when bend the throttle and signal do not change, the clamping stagnation of signal is constant；
5th, when 3 road signal proportions are different from preset ratio relationship west, signal has deviation.
In the above description, U can be U1, U2 and U3, and U0 refers to the actual power voltage of each detection port.
Controller 120 is as follows for the processing of failure：
Under normal condition, the signal that pedal position sensor 110 exports is Sensor1：Sensor2：Sensor3=3:2:
1, when one of sensor signal generation 1,2,3,4,5 failure, ignore fault-signal value, No. 3 signal transducers can become 2
Road signal transducer can equally carry out the verification of signal, continue the control of vehicle.Although pedal position sensor 110
It is likely to occur two signals and 1,2,3,4,5 failures occurs, but failure rate is than 1 road signal failure in No. 2 signal transducers
Probability is much lower, therefore, has higher reliability.In addition, when sensor only has 1 road signal can be used, vehicle enters crawling,
I.e.：Controller 120 in the first detection port, the second detection port and third detection port is determined two there are during failure, control
Vehicle processed enters crawling pattern.
In the above description, pedal can be accelerator pedal, and therefore, pedal position detection device is examined for accelerator pedal position
Device is surveyed, similarly, pedal position sensor refers to accelerator pedal position sensor.
According to the pedal position detection device of the utility model embodiment, detect signal by 3 tunnels and verify, it can be 1
When road detection signal breaks down, vehicle is normally controlled, increases the safe class of pedal position detection device, promotes pedal position
The ability of detection device reply failure is put, reduces the appreciable failure rate of client.
Further, as shown in Figure 1, the embodiment of the utility model discloses a kind of vehicle, including：According to above-mentioned arbitrary
The pedal position detection device of one embodiment.The pedal position detection device of the vehicle detects signal by 3 tunnels and verifies, can
When 1 tunnel detection signal breaks down, normally to control vehicle, increase the safe class of pedal position detection device, be promoted
Pedal position detection device copes with the ability of failure, reduces the appreciable failure rate of client, promotes the usage experience of vehicle.
