Patent number: 8641070Abstract: A drive assistance device for a wheelchair includes a drive motor, a running wheel and a sensor device which is adapted to determine a driving force manually induced into the running wheel; and a control unit which is adapted to control the drive motor for driving the running wheel depending on the driving force manually induced by the user into the running wheel. The control unit of the drive assistance device includes a user force analysis operational mode which is adapted to determine data concerning physical efficiency and capacity of the user. These include a maximum force of the user as well as the maximum speed which can be reached with purely manual drive.Type: GrantFiled: September 7, 2011Date of Patent: February 4, 2014Assignee: Ulrich Alber GmbHInventors: Thomas Birmanns, Ralf Ledda, Bernd Engels, Paul-Gerhard Bitzer
