What are the functions of Lexus B gear?
2 Answers
Lexus B gear mainly has the following functions: 1. B gear stands for brake, which means engine braking. This gear can be used when going downhill. Engaging B gear while descending will utilize the motor's intervention to achieve the effect of engine braking. 2. When descending long and steep continuous slopes, relying solely on the braking system for deceleration is very dangerous. That's why Lexus is equipped with B gear. 3. B gear primarily brakes the engine's output to decelerate. The energy generated by decelerating with B gear will be recycled to charge the vehicle's battery.
I often use the B gear when driving my Lexus RX, especially on downhill sections in mountainous areas. It helps decelerate through engine braking, reducing the burden on the brakes. Once, when driving down from a mountain peak, I used the B gear and felt the car automatically slow down with more stable steering, avoiding the danger of overheated brakes. The B gear is very practical on steep slopes or in rainy/snowy conditions, maintaining speed control and enhancing driving safety. In hybrid vehicles, the B gear also affects the energy recovery system, potentially slightly increasing fuel consumption but protecting battery life. During daily city driving, if there's traffic congestion or anticipated deceleration points, switching to B gear can make the ride smoother and reduce sudden braking. Overall, it's an intelligent driving assistance feature that enhances my driving experience and vehicle durability.
