Why does the Audi A4 experience jerking when accelerating at low speeds?

[DeJuliette]

Audi A4 experiences jerking when accelerating at low speeds because the vehicle's computer has a relatively vague boundary between idle coasting and acceleration, leading to delays and resulting in jerking. Automotive Power Performance: Automotive power performance refers to the average driving speed that a vehicle can achieve when driving straight on good road surfaces, determined by the longitudinal external forces acting on the vehicle. It is one of the most fundamental and important performance metrics of a car. It is primarily evaluated based on three indicators: maximum speed, acceleration time, and maximum gradient. Vehicle Acceleration Time: Vehicle acceleration time is commonly evaluated using the standing start acceleration time and the overtaking acceleration time. The standing start acceleration time refers to the time required for a vehicle to accelerate from a standstill to a predetermined distance or speed with maximum acceleration. The overtaking acceleration time refers to the time required for a vehicle to accelerate from a certain lower speed to a higher speed with full power.
