L4 autonomous driving belongs to "highly autonomous driving." Except for certain special circumstances, human intervention is generally not required. Autonomous vehicles that rely on specialized maps for operation fall under Level 4 autonomous driving. As long as there is a map, these vehicles can achieve full autonomous driving without human intervention, but they cannot drive autonomously everywhere. Below is an introduction to autonomous driving levels: 1. Level 0: No automation. The driver must always be in control of all mechanical and physical functions of the vehicle, with only alarms as assistance. 2. Level 1: The driver operates the vehicle, but individual devices can sometimes assist, such as Electronic Stability Program (ESP) or Anti-lock Braking System (ABS), which can help with driving safety. 3. Level 2: The driver primarily controls the vehicle, but the system offers partial automation to significantly reduce the operational burden. For example, Adaptive Cruise Control (ACC) combines automatic following and lane departure warnings, while Autonomous Emergency Braking (AEB) integrates blind-spot detection and partial collision avoidance system technologies. 4. Level 3: The driver must always be ready to take control of the vehicle. During autonomous driving assistance, such as when following another vehicle, the driver can temporarily be free from operation. However, when the vehicle detects a situation requiring the driver's intervention, it will immediately return control to the driver, who must take over in cases the system cannot handle.

What does TC mean when displayed on the car?

When TC is displayed on the car, it indicates that the Traction Control System (TCS) is in operation. The Traction Control System, also known as ASR or TRC, ensures that the vehicle achieves optimal traction under various driving conditions. When used in conjunction with ABS, the Traction Control System further enhances the vehicle's safety performance. The Traction Control System and ABS can share wheel speed sensors on the axle and are connected to the vehicle's onboard computer, continuously monitoring the speed of each wheel. If wheel slip is detected at low speeds, the Traction Control System immediately signals the ABS to act, reducing the slip of the affected wheel. If wheel slip is detected at high speeds, the Traction Control System sends a command to the onboard computer to reduce engine speed or downshift the transmission, preventing the wheel from slipping further and avoiding loss of control or fishtailing.
