Do automatic transmission cars need to engage the handbrake when parking?

[SilasDella]

Automatic transmission cars need to engage the handbrake when parking. When parking, the electronic handbrake of an automatic transmission can be engaged either by shifting into P gear first and then pulling up the handbrake, or by pulling the handbrake first and then shifting into P gear. However, if you pull the handbrake first and then shift into P gear, the driver's foot must remain on the brake pedal and cannot be released. This is because the automatic transmission contains a hydraulic transmission mechanism, and the flow of hydraulic fluid has a certain inertia that cannot change abruptly. Below are the advantages of electronic handbrakes: 1. Eliminating the mechanical brake handle inside the car provides more design flexibility for the interior styling. 2. The parking brake is completely replaced by a single button instead of a manual parking brake handle. 3. Additionally, electronic handbrakes are more reliable than mechanical handbrakes.
