A bypass energy storage device for an electronically controlled hydraulic braking system includes a brake master cylinder, a first pipeline, and a second pipeline. The first pipeline is connected with a first branch. One end of the first branch is communicated to an energy accumulator, and the first branch is connected with a first inlet valve. The second pipeline is connected with a second branch. One end of the second branch is communicated to the energy accumulator, and the second branch is connected with a second inlet valve. The energy accumulator is communicated with a third branch, and one end of the third branch is communicated to a second pipeline. The effects of reducing energy consumption, better controlling foot feeling and thus improving the comfort and safety of products are achieved.

Bypass energy storage device for electronically controlled hydraulic braking system and control method thereof

An automobile electronic parking execution controller with a double-MCU redundancy design comprises a parking switch circuit, a biaxial acceleration sensor unit, a main micro control unit (MCU) Uand a monitoring MCU U, wherein the main MCU Ucontrols a parking motor by means of detecting signals of the parking switch circuit and the biaxial acceleration sensor, the monitoring MCU Umonitors a running state of a whole control system and restores the main MCU Uwhen the main MCU Uis abnormal, and the main MCU Urestores the monitoring MCU Uwhen the monitoring MCU Uis abnormal. After the main MCU Ucrashes, the main MCU Ucan still be quickly stored through the monitoring MCU U, so that the main MCU Uquickly enters a response state to recover the parking brake control ability, which improves the safety of the system.

An electro-hydraulic braking system includes a main casing. A hydraulic unit brake master cylinder is provided in the main casing. An outer end of a piston rod of the brake master cylinder is connected to an output top rod. Another end of the output top rod is provided with an input rod. The input rod is slidably connected in the main casing along only a length direction of the input rod, and another end of the input rod is provided with a push rod that is configured to transmit a brake pedal force. The main casing is further provided therein with a reset member configured to push the push rod away from the brake master cylinder to reset and a displacement sensor configured to sense a displacement of the push rod. The input rod and the output top rod include a spacing state and an abutment state.
