摘要: In order to reduce errors in the determination of reference speed a vehicle from wheel speeds, invention provides first step for speeds each be multiplied by associated radius, obtain circumferential wheel. this case, radius is assumed constant radial tyres normally occurring. Depending on driving situation (driving, engine coasting (overrun condition) and braking), derived one or more wheels. Consideration given group wheels which runs during acceleration with least traction slip brake slip. event delays simultaneous occurrence high transverse (lateral) (braking turn), having highest load are decisive speed. Thereafter, arithmetic mean formed selected time window of, example, 300 ms, vehicle.
