車両の始動スイッチがオフされた場合、シフトレンジ切替システムでのPレンジへの切り替えが完了した場合、または、P作動指令から判定時間が経過した場合、シフト制御部の電源をオフにし、シフトレンジからP作動完了通知またはP不可異常が生じている旨の情報をブレーキ制御部が受信した場合、もしくは、P作動指令から判定時間が経過した場合、電動パーキングブレーキ装置を作動させ、電動ブレーキ装置の作動完了後にブレーキ制御部の電源をオフにする。
以下、本発明による車両用制御装置を図面に基づいて説明する。図1に示すように、車両用制御装置100は、車両制御システム1を制御するものであって、車両制御システム1には、シフトレンジ切替システムとしてのシフトバイワイヤシステム2、および、電動ブレーキシステム3が含まれる。電動ブレーキシステム3には、ブレーキバイワイヤ装置61および電動パーキングブレーキ装置62が含まれる。以下適宜、シフトバイワイヤを「SBW」、ブレーキバイワイヤを「BBW」、電動パーキングブレーキを「EPB」と記載する。
上記実施形態では、レンジ不一致異常が生じた場合、BBW装置61を作動させて車両を固定する。他の実施形態では、レンジ不一致異常が生じた場合、BBW装置61に加え、EPB装置62を作動させてもよい。また、BBW装置61に替えて、EPB装置62を作動させてもよい。上記実施形態では、電動ブレーキシステムには、BBWシステムおよびEPBシステムが含まれるが、いずれか一方がメカ式のものであってもよい。また、電動ブレーキシステムはブレーキ制御装置により制動を制御可能であれば、上記実施形態の構成に限らず、どのような構成であってもよい。
