Problems solved by technology

[0003] like figure 1 As shown, the existing control process when the whole vehicle goes down a long slope is as follows: the whole vehicle starts to go down a long slope——the driver puts in a certain gear and reaches an appropriate set speed——the driver presses the engine brake button of the whole vehicle ——ECU (Electronic Control Unit, Electronic Control Unit) controls to turn on the engine braking mode, and turn on all the brake solenoid valves ——The driver adjusts the gear according to the speed change or applies the service brake ——The vehicle speed is maintained at the set speed Nearby; however, when the vehicle goes down a long slope, the driver needs to select a gear for engine braking. If the selected gear is too low, the engine braking force will be large at the same speed, so the vehicle speed is often low; if the selected gear If it is too high, the engine braking force is insufficient at the same speed, and the driver needs to use the service brake frequently to reduce the vehicle speed. The movement also increases the driver's work intensity

Abstract

The invention relates to the technical field of whole vehicle braking and discloses an engine braking system. The engine braking system comprises an ECU, a main oil gallery, three braking electromagnetic valves and six braking rocker arms which corresponds to six air cylinders of an engine in a one-to-one mode. The ECU is connected with the three braking electromagnetic valves individually through braking electromagnetic valve wiring harnesses. An oil way of one braking electromagnetic valve communicates with two braking rocker arms. Oil ways of the three braking electromagnetic valves are connected to the main oil gallery. The invention further provides a whole vehicle braking cruise control method applying the engine braking system. According to the engine braking system and the whole vehicle braking cruise control method applying the engine braking system, the whole vehicle road safety during long downhill of a whole vehicle can be improved and the labor intensity of a driver is relieved.

Description

technical field [0001] The invention relates to the technical field of vehicle braking, in particular to a vehicle braking cruise control method using an engine braking system. Background technique [0002] At present, when most vehicles go down a long slope with a full load or a heavy load, the engine brake must be turned on in a certain gear, and combined with intermittent service brake to control the vehicle speed. Select the appropriate gear according to the vehicle load and other conditions, and apply appropriate service brakes according to the speed of the vehicle. [0003] Such as figure 1 As shown, the existing control process when the whole vehicle goes down a long slope is as follows: the whole vehicle starts to go down a long slope——the driver puts in a certain gear and reaches an appropriate set speed——the driver presses the engine brake button of the whole vehicle ——ECU (Electronic Control Unit, Electronic Control Unit) controls to turn on the engine braking m...
