Introduction
The purpose of the ESP module is to make your wheelchair safer to use. ESP
stands for Enhanced Steering Performance.
The ESP module is programmed by Permobil to give the wheelchair optimal
performance. Individual adaptations can mean that minor adjustments may be
required at a later date. The preprogrammed parameters may only be adjusted
by technicians familiar with the ESP module.
The ESP module is installed in the wheelchair chassis. See the service manual
for the chassis for further information.
The ESP module is connected to the wheelchair control system. The module
contains a sensor that measures any course deviations made by the wheelchair.
A processor uses this information to correct any deviations from the course set
by the user using the wheelchair’s steering device. The ESP module uses the
information from the sensor and the steering device to calculate a corrected
steering signal. The steering signal is then passed on to the wheelchair’s R-Net
output stage, which controls the drive motors.
The function of the ESP module requires access to the full capacity of the output
stage. These different parameters must therefore be adjusted to their maximum
values or to other predefined values.
NB. The parameters for the output stage, Power Module (PM), are set by
Permobil and must not be changed. The ESP module has integral functions
for controlling the wheelchair’s performance, acceleration, course stability,
etc. If any changes are required to the way the wheelchair is operated, the
ESP module must be reprogrammed.
