Title:
車両の算出装置
Document Type and Number:
Japanese Patent JP7025261
Kind Code:
B2
Abstract:
To make it possible to perform a determination of a rotation direction of a rotor and a calculation of a rotation speed of the rotor even when an implementation of cut-in processing caused by an edge input into a port is delayed.SOLUTION: An electronic circuit 30 of a calculation device 20 has: a first port 41 and second port 42 to which a pulse signal is input; a port register 43 in which edge time information is stored; a timer 44 that counts an ON time; and a CPU 36. In the electronic circuit 30, when a rising edge is input into the first port 41, an implementation of first cut-in processing is requested to the CPU 36. When a falling edge is input into the second port 42, an implementation of second cut-in processing is requested to the CPU 36. The CPU 36 is configured to determine rotation directions of wheels 11 to 14 on the basis of the ON time stored in a RAM 38 due to the implementation of the second cut-in processing; and calculate rotation speeds of the wheels 11 to 14 on the basis of the edge time information stored in the RAM 38 due to the implementation of the first cut-in processing.SELECTED DRAWING: Figure 1
