What is the function 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 using B gear for deceleration will be recycled to charge the vehicle's battery.
I drive a Lexus hybrid and particularly love the design of the B gear, which is a braking or deceleration gear mainly used for long downhill conditions. When driving normally in D gear, everything works fine, but as soon as I encounter a slope, I switch to B gear. The combination of the engine and electric motor provides additional braking force, allowing the car to slow down on its own without frequent brake pedal use like in conventional cars. This feature not only protects the brake pads from excessive wear but also recovers energy to recharge the battery, making the overall hybrid system more efficient and fuel-saving. I often use it when traveling in mountainous areas, especially in rainy or slippery conditions, as it helps the car maintain stable speed control. I recommend getting familiar with the gear-shifting operation and avoiding using it on flat roads to prevent increased fuel consumption. Overall, it's a practical and eco-friendly innovative design.
