A printer system is associated with a taximeter for calculating the taxi fare, a seat switch for detecting a passenger who occupies the taxi, and a timepiece. A printer driver functions to drive the printer to record a drive condition of a taxi and time information each time when the drive condition is changed, for example, from 'for hire' wherein the taxi is not occupied by the passenger and no fare is computed to 'occupied' wherein the taxi is occupied by the passenger and the taxi fare is computed through the use of a predetermined tariff.

An anti-skid brake control system wherein the brake force is automatically reduced in response to the relationship between the sensed values of the vehicle velocity and the wheel velocity, may erroneously operate at an undesired time when the vehicle is making a turn. The above-mentioned erroneous operation is caused by the misdetermination of the vehicle velocity which based on the difference of the velocities between the outside rear wheel and the inside rear wheel while making the turn. To avoid the erroneous operation, a steering wheel sensor is provided for sensing the angle of a steering wheel. Output signals of the steering wheel sensor are applied to a compensation circuit for compensating output signals of a wheel sensor which detects the velocity of the wheel of a wheeled vehicle, the detected value being used for the determination of the velocity of the vehicle, for the purpose of minimizing the difference of the wheel velocities.
