A more intelligent chassis can meet the development needs of vehicle electrification and intelligence. The new requirements for smart chassis can be summarized into four categories:
● Personality: provide personalized customization according to customer driving habits
● High performance: the system responds more accurately and quickly
● Can grow: the system has self-learning ability and supports OTA upgrade
● High security: multiple security guarantees for product security and information security
Although judging from the current market performance, the chassis system is still in the electromechanical hybrid period, but we can already see the trend of transition to intelligent chassis. The first is the popularization and evolution of wire control technology in cars. The wire control technology originates from the aircraft control system, which converts the pilot’s control commands into electrical signals, and transmits them directly to the autonomous steering gear through cables. The biggest advantage of wire control technology is precise and rapid response, which has been inherited in automotive wire control technology. At present, each chassis control subsystem has basically realized wire control. As autonomous driving evolves, the role of the driver is diminished, with the role of the steering wheel and pedals diminishing. The decoupling of the electronic control system and the driver’s mechanical interface can more flexibly adjust the characteristics of the chassis system to meet the individual needs of different customers. This is another advantage of the drive-by-wire chassis.
