What are the activation conditions for the automatic emergency braking system in the 2021 Corolla?
2 Answers
The automatic emergency braking system in the 2021 Corolla is enabled by default. This system activates when a collision is imminent but the driver fails to apply the brakes, thereby reducing the driver's workload to some extent. Additional information about the Corolla is as follows: Powertrain: Taking the Corolla 2021 1.2T S-CVT Elite PLUS version as an example: It is a compact 4-door 5-seater sedan, equipped with a 1.2T inline 4-cylinder engine. The engine delivers a maximum horsepower of 116 hp and a maximum torque of 185 Nm. The drivetrain configuration is front-engine, front-wheel drive. The front suspension employs a MacPherson strut independent suspension, while the rear suspension uses an E-type multi-link independent suspension.
When I first drove the 2021 Corolla, I heavily relied on its pre-collision system. The activation conditions mainly fall into several scenarios: First, if the vehicle ahead suddenly slows down or stops, the system uses the front radar and camera to detect the distance. If I don't brake in time beyond the safe range, it will initiate braking. Second, when encountering pedestrians or bicycles crossing the road, the system is more likely to activate at speeds between 15 to 80 km/h, such as when a car suddenly cuts in during traffic congestion. Third, when the system judges a high collision risk, it first emits a warning sound. If I don't react within two seconds, it automatically applies the brakes. I also noticed the system responds slightly slower in rain or snow, so I recommend regularly cleaning the sensors with a soft cloth to ensure road clarity. This feature is particularly useful during highway driving or in crowded urban areas, but remember it's only an assist—staying focused as a driver is more crucial. Don't assume the automatic system can replace human response to all unexpected situations.
