Since electronic signal transmission is faster than mechanical connection, wire-controlled can provide a higher level of safety protection for intelligent driving.

'Short response time plus strong scalability' is a necessary feature for advanced intelligent driving. Compared with the traditional braking system, the brake-by-wire replaces the mechanical force by the electronic signal, and the braking can be realized without the intervention of external force. demand and control the brakes individually. After the pedal stroke sensor measures the displacement of the input push rod, the displacement signal is sent to the ECU, and the ECU calculates the braking request the ECU can also actively generate the brake according to the needs of the scene. The brake signal of the brake-by-wire system can come from the pedal.

The transmission of brake execution information by electronic signals is the basis for realizing intelligent driving.

The current mainstream products in the industry, such as the Bosch iBooster, have gotten rid of them. Therefore, the first-generation brake-by-wire system uses an electronic vacuum pump to solve the dependence on the engine to provide negative pressure, but there are problems of loud noise and poor performance at high altitudes. The initial development of brake-by-wire is mainly due to the fact that hybrid and pure electric vehicles do not have a continuous working engine to provide a stable negative pressure to support the vacuum booster. It is difficult for PHEVs and EVs to support vacuum assist. (1) Why is the brake-by-wire system a key link towards intelligent driving? The development of the future braking system will enter the fourth stage, that is, the brake-by-wire with redundant mechanism, which is mainly developed to adapt to a higher level of intelligent driving. The development of automobile braking system has mainly gone through three stages of 'hydraulic braking-hydraulic braking fusion electronic control-wire-by-wire'. Brake-by-wire: matching the needs of high-level intelligent driving, there is still a lot of room for technological change The core reasons why wire-controlled technology has become a key part of intelligent driving are: 1) Electric signal transmission is faster than mechanical connection, and wire-controlled can provide a higher level of safety protection for intelligent driving 2) wire-controlled is more suitable for the development trend of high integration, in order to achieve the goal of chassis domain control.ģ.1. We believe that in the future, the control-by-wire system may be fully integrated into the chassis domain controller to match higher-level intelligent driving needs.

The key in terms of steering, EPS (electric power steering system) can meet the current needs of intelligent driving, and the steering-by-wire is still on the eve of mass production.

It has become the 'standard', and the technical threshold for shift-by-wire is low, and it also basically achieves full coverage in terms of braking, the popularity rate of brake-by-wire is relatively low, and the technical threshold is high, which is the most meaningful for realizing intelligent driving. On vehicles with ACC (Adaptive Cruise Control) and TCS (Traction Control System) functions, the accelerator-by-wire has the highest penetration rate. Under the wave of intelligence, the penetration rate of wire-controlled technology, which replaces mechanical force with electrical signals, has risen sharply in the era of intelligent driving.Īmong the three independent control-by-wire systems, the drive-by-wire accelerator has the highest penetration rate. The above operating mechanism is called execution by wire, which mainly includes the throttle, steering and braking by wire.

When the driver completely transfers the driving control of the vehicle to the on-board computer system of the intelligent driving vehicle, the electronic signal replaces the mechanical hydraulic method to control the steering wheel, accelerator and braking system. The executive layer is the bottom layer of car driving, and its core operating mechanism is to enable the car to drive stably through the cooperation of the driving, braking and steering control systems.
