Publication number: 20150203121Abstract: Heart rates of the driver are recorded at a deceleration start time when a vehicle in a travelling state starts to decelerate and stop. The heart rates within a predetermined period recorded before the deceleration start time by the biological information record unit are referred to, and a pre-deceleration heart rate which is a representative value of the referred heart rates is extracted. Furthermore, the heart rates within a predetermined period recorded after the deceleration start time by the biological information record unit are referred to and a post-deceleration heart rate which is a representative value of the referred heart rates is extracted. Then, the pre-deceleration biological information and the post-deceleration biological information extracted by the biological information extraction unit are compared with each other to estimate the steady state of the driver after deceleration.Type: ApplicationFiled: June 14, 2013Publication date: July 23, 2015Applicant: Nissan Motor Co., Ltd.Inventors: Souichirou Mori, Youji Shimizu, Hiroaki Miura, Yasuhiro Fukuyama, Takashi Sunda
