Embodiment 1
[0054] The invention is a method for controlling the opening threshold and closing threshold of a brake vacuum pump, comprising the following steps:
[0055] Information obtaining step: obtain current vehicle speed information and braking information.
[0056] Threshold setting step: through the current vehicle speed information and braking information, set the opening threshold and closing threshold of the vacuum pump respectively according to the speed of the vehicle and the magnitude of the braking signal. Under the premise of ensuring braking safety, reduce Working hours of the vacuum pump.
[0057] As other alternative implementations, in addition to the above-mentioned vehicle speed information and braking information, thresholds can also be set in conjunction with current vehicle operating conditions such as road conditions, vehicle performance and other parameters, and these values are used to set the opening threshold and threshold of the vacuum pump. When closing ...
Embodiment 2
[0080] As an embodiment of the present invention, on the basis of Embodiment 1, it also includes the step of correcting the opening threshold and closing threshold of the vacuum pump according to the current atmospheric pressure, and the step of correcting the atmospheric pressure further includes the following steps:
[0081] Collect the current outside atmospheric pressure.
[0082] The atmospheric pressure correction coefficient is obtained by dividing the current external atmospheric pressure by the standard atmospheric pressure.
[0083] The atmospheric pressure correction coefficient is multiplied by the obtained vacuum pump opening threshold and the vacuum pump closing threshold, and the obtained values are respectively used as the final vacuum pump opening threshold and closing threshold.
[0084] The invention can adjust the opening and closing of the vacuum pump according to the current atmospheric pressure, and further enhances the performance of the vehicle braki...
Embodiment 3
[0086] The present invention is a control system for opening threshold and closing threshold of brake vacuum pump, such as figure 2 shown, including:
[0087] The information obtaining device is used for obtaining at least current vehicle speed information and braking information.
[0088] The threshold setting device is used to respectively set the opening threshold and the closing threshold of the vacuum pump according to the current vehicle speed information and the braking information. Through the current vehicle speed information and the braking information, at least according to the speed of the vehicle and the magnitude of the braking signal Set the opening threshold and closing threshold of the vacuum pump separately, and reduce the working time of the vacuum pump under the premise of ensuring braking safety.
[0089] As other alternative implementations, in addition to the above-mentioned vehicle speed information and braking information, thresholds can also be set ...
