Previously large number of drivers in many cities have complained about poor braking performance under some conditions. It will see new software loaded into the car that should improve braking while ABS is active at low speeds, the company said.
In normal driving conditions, the cars use hydraulic brakes and a regenerative braking system to recover energy as they slow down, but when the ABS cuts in, the cars switch to hydraulic braking only, which can result in reduced braking performance and a longer stopping distance.

The problem only occurs under soft braking,
said. Applying increased pressure on the brake pedal when ABS is in operation will give better brake performance, the company said. Toyota
