The system does not give the LEAF more torque - it takes away the electronic babysitters.sparky wrote:That's the first I've heard of that technique for more torque.
LEAFs stability control (vehicle dynamic control or VDC) also incorporates a traction control system (TCS). TCS comes into play when taking off from a standing start. VDC comes into play while driving on slippery curvy roads. Both control the application of power to the ground.
In a nutshell, VDC/TCS uses the ABS wheel sensors to monitor wheel spin. In a front-drive car if the rear wheels are turning at XX mph and the front tires are spinning at anything faster, TCS modulates the accelerator application for you via the LEAFs drive-by-wire throttle to reduce/eliminate wheel spin. Turn off VDC and you turn off TCS. Turn off TCS and you spin the front tires with 200+ immediate pounds of torque applied at 0 mph.
VDC takes it one step further. When driving on a curvy road and the vehicle senses wheel spin, especially in concert with the vehicle going in an unintended direction (steering wheel sensor incorporated with a yaw sensor), it will reduce throttle application and brake any wheel individually to properly re-orient the vehicle. VDC/stability control systems go a long way toward reducing single car collisions.
