摘要： A vehicle running control system includes: a steering apparatus that includes a turning device being mechanically separated from a steering wheel; a vehicle drive unit; and a control device. The control device is configured to execute: a turning processing that controls the turning device such that an actual turning angle of the wheel approaches a target turning angle; a vehicle driving processing that determines a target vehicle driving force according to a required vehicle driving force based on a vehicle driving request and that controls the vehicle drive unit so as to cause an actual vehicle driving force to the target vehicle driving force determined; and where a turning angle difference is greater than a turning angle threshold value in a low vehicle speed condition, a driving force limiting processing that limits the target vehicle driving force so as to become smaller than the required vehicle driving force.

摘要： A receiver receives frames transmitted by transmitters respectively attached to wheel assemblies. Each transmitter transmits three or more frames successively at different transmission intervals when a rotation angle of the associated wheel assembly agrees with a specific angle. When receiving the frames, the receiver determines the transmission ordinal numbers of the received ones of the frames from a previously stored correspondence relationship between an order of transmission and transmission intervals of the frames. The receiver derives, from the determined order of transmission of the frames, a specific point in time that is within specified time from the detection of the specific angle. Based on the rotation angle of the wheel obtained by a rotation angle detecting unit at the specific point in time, the receiver identifies the wheel assembly to which each of the transmitters is attached.

摘要： A transmitter is configured to be attached to each of wheel assemblies in a vehicle and execute a process in accordance with a command included in a trigger signal. The transmitter includes a condition detecting section, a trigger receiving section which receives, as the trigger signal, an unmodulated wave having a received signal strength indication a transmitting section, and a controlling section. When the trigger receiving section receives the unmodulated wave, the controlling section causes the transmitting section to transmit the signal in response to the unmodulated wave. The controlling section is configured to execute an accumulation process to accumulate reception time of the unmodulated wave from a starting point in time, and shift into a restriction state to restrict a response to the unmodulated wave when the accumulated reception time reaches a predetermined time.

摘要： A reception control section obtains the rotation angles of wheel assemblies when receiving transmission data by a reception circuit. The reception control section divides 360°, which is the range of the possible rotation angles of the wheel assembly, into equal parts to obtain angle ranges and assigns each of the obtained rotation angles to one of angle ranges. The reception control section derives the angle range in which the number of times (frequency) the obtained rotation angles are included is a maximum value. The reception control section calculates a reception-side angle difference, which is the difference between the median values of the angle ranges in which the number of times the obtained rotation angle is included is a maximum value. The reception control section associates the ID codes with the wheel assemblies based on the correspondence between the reception-side angle difference and the angle difference between specific angles.
