Abstract

A truck and a bodybuilder module for a truck, a method, a memory and software to configure the bodybuilder module are provided. The truck includes a first non-volatile memory zone, content of which cannot be modified, the first non-volatile memory zone storing authorized mathematical operators and a plurality of authorized operands, each operand corresponding to a data generated by one of the electronic control units or one of the sensors, a second non-volatile memory zone, content of which can be modified, the second non-volatile memory zone storing information defining a mathematical operation, the mathematical operation being formed by a combination of operators and operands, a microprocessor able to execute the mathematical operation defined by the information stored in the second non-volatile memory zone only if each of the operators and operands of the defined mathematical operation matches an authorized operator or operand stored in the first non-volatile memory zone, and to transmit the result of the executed mathematical operation to the auxiliary unit through the auxiliary unit connection.

Dependent claims

Truck comprising:

a plurality of electronic control units able to control actuators of the truck and/or sensors, the control unit and the sensors being able to generate respective data that represent the operative state of the truck,
a bus linking together the electronic control units and the sensors,
a bodybuilder electronic module connected to the bus, the electronic module comprising an auxiliary unit connection to connect an auxiliary unit chosen amongst a plurality of different auxiliary units which can be installed on this truck, each auxiliary unit being able to drive an auxiliary equipment added to the truck after its construction, this connection being able to transmit, to the auxiliary unit, information on the operating state of the truck which is built from data read on the bus, and
a configuration connection to connect and, alternatively, to disconnect a configuration computer to the bodybuilder electronic module,
a first non-volatile memory zone, content of which cannot be modified through the configuration connection, the first non-volatile memory zone storing a first predetermined list of authorized mathematical operators and a second predetermined list of a plurality of authorized operands, each operand corresponding to a data generated by one of the electronic control units or one of the sensors,
a second non-volatile memory zone, content of which can be modified through the configuration connection, the second non-volatile memory zone storing information defining a mathematical operation, the mathematical operation being formed by a combination of operators and operands,
a microprocessor able:
to execute the mathematical operation defined by the information stored in the second non-volatile memory zone only if each of the operators and operands of the defined mathematical operation matches an authorized operator or operand stored in the first non-volatile memory zone, and
to transmit the result of the executed mathematical operation to the auxiliary unit through the auxiliary unit connection.

A method to configure a bodybuilder electronic module of a truck, the method comprising:

providing the bodybuilder electronic module with:
an auxiliary unit connection to connect an auxiliary unit chosen amongst a plurality of different auxiliary units which can be installed on this truck, each auxiliary unit being able to drive an auxiliary equipment added to the truck after its construction, this auxiliary unit connection being able to transmit, to the auxiliary unit, information on the operating state of the truck which is built from data read on the bus,
a first non-volatile memory zone, content of which cannot be modified through the configuration connection, the first non-volatile memory zone storing a first predetermined list of authorized mathematical operators and a second predetermined list of a plurality of authorized operands, each operand corresponding to a data generated by one of the electronic control units or one of the sensors,
a second non-volatile memory zone, content of which can be modified through the configuration connection, the second non-volatile memory zone storing information defining a mathematical operation, the mathematical operation being formed by a combination of operators and operands,
a microprocessor able:
to execute the mathematical operation defined by the information stored in the second non-volatile memory zone only if each of the operators and operands of the defined mathematical operation matches an authorized operator or operand stored in the first non-volatile memory zone, and
to transmit the result of the executed mathematical operation to the auxiliary unit through the auxiliary unit connection,
displaying mathematical operators and operands in respective list zones, each list zone being populated only with the authorized mathematical operators and operands, respectively,
acquiring the operator and operand selected by an operator in the list zone to define a mathematical operation, and
downloading the defined mathematical operation into the second nonvolatile memory zone from a computer connected to the module through the configuration connection.
