What Does Electronic Limited Slip Mean?
2 Answers
Electronic Limited Slip, also known as inter-wheel electronic limited slip, is developed based on the ESP (Electronic Stability Program) system. The ESP version of Dmax is the Bosch integrated ESP 9.1. Its working principle is similar to that of ESP. Under special road conditions, when the computer detects that a single wheel is slipping, it briefly applies the brake and then releases it. This stops the wheel from spinning, allowing it to regain contact with the ground and increase traction to aid in escaping difficult situations. Below is an extended introduction: 1. Principle of Electronic Limited Slip: The principle and structure of electronic limited slip are quite simple. When the computer detects wheel slip, it automatically controls the brakes, applying resistance individually to the slipping or lifted wheel. Due to the presence of the differential, when the forces on the two wheels on the same axle are unequal, the wheel with less resistance receives more torque. Therefore, by braking the spinning wheel, not all the power is applied to the slipping wheel, allowing some power to be transferred to the grounded wheel for escape. 2. Advantages and Disadvantages of Electronic Limited Slip: The characteristic of electronic limited slip is its simple structure, as it relies on the existing braking system and does not require additional mechanical components. The downside is that it is not suitable for high-intensity off-roading and has a slower response time. It requires a sufficient speed difference between the two wheels to activate, and its slip-limiting capability is generally moderate.
Driving friends all know how scary slippery roads can be, and electronic traction control is a real lifesaver in such situations. I remember last month when I was driving into the mountains - the muddy road after rain was incredibly slippery. Suddenly, my right front wheel started spinning out, but before I could even react, the car automatically braked the spinning wheel and transferred power to the left wheel, allowing me to continue driving steadily. The principle is actually that the car's computer constantly monitors wheel speed, and when it detects any wheel spinning, it immediately brakes that wheel to let the other wheel with traction take over. It's much more practical than traditional mechanical locks, especially for urban SUVs on snow or gravel roads. While it can't completely lock like a differential lock, it's perfectly sufficient for daily off-road situations. My Highlander has this feature, and the technician during maintenance said to regularly check the wheel speed sensors to prevent delayed response.
