It is advisable to engage the handbrake for automatic transmission cars. Below is relevant information about automatic transmissions: 1. Transmission Types: There are primarily two types of automatic transmissions used in vehicles. One is the stepped automatic transmission, and the other is the continuously variable transmission (CVT). The most commonly used in passenger cars is the mechanical CVT, which utilizes a V-shaped metal belt or chain to transmit torque between the driving and driven pulleys in their V-shaped grooves. This transmission method is typically used in smaller vehicles. 2. Operational Characteristics: In modern automatic transmission cars, the driver only needs to control the accelerator pedal. The computer analyzes signals from sensors that detect the engine throttle opening and vehicle speed, automatically controlling gear shifts or engaging different gears. Generally, automatic transmissions result in some power loss from the engine. The greatest advantage of automatic transmission vehicles is convenience, especially in traffic jams or when encountering uphill slopes during congestion, where their benefits become even more apparent. Nowadays, automatic transmission cars are becoming increasingly popular. From the perspective of advanced automotive development countries, most vehicles are transitioning to fully automatic transmissions. The replacement of manual transmissions by automatic transmissions as the primary model for daily driving is a trend in automotive development.
